Grace means undeserved kindness.

It is the gift of God to man

the moment he sees he is unworthy of God’s favor.

~ Dwight L. Moody

[And Jesus said:] "For the kingdom of heaven is like a landowner who went out early in the morning to hire laborers for his vineyard. After agreeing with the laborers for the usual daily wage, he sent them into his vineyard. When he went out about nine o'clock, he saw others standing idle in the market-place; and he said to them, 'You also go into the vineyard, and I will pay you whatever is right.' So they went. When he went out again about noon and about three o'clock, he did the same. And about five o'clock he went out and found others standing around; and he said to them, 'Why are you standing here idle all day?' They said to him, 'Because no one has hired us.' He said to them, 'You also go into the vineyard.' When evening came, the owner of the vineyard said to his manager, 'Call the laborers and give them their pay, beginning with the last and then going to the first.' When those hired about five o'clock came, each of them received the usual daily wage. Now when the first came, they thought they would receive more; but each of them also received the usual daily wage. And when they received it, they grumbled against the landowner, saying, 'These last worked only one hour, and you have made them equal to us who have borne the burden of the day and the scorching heat.' But he replied to one of them, 'Friend, I am doing you no wrong; did you not agree with me for the usual daily wage? Take what belongs to you and go; I choose to give to this last the same as I give to you. Am I not allowed to do what I choose with what belongs to me? Or are you envious because I am generous?' So the last will be first, and the first will be last."

Exodus 16:2-15

The whole congregation of the Israelites complained against Moses and Aaron in the wilderness. The Israelites said to them, "If only we had died by the hand of the Lord in the land of Egypt, when we sat by the fleshpots and ate our fill of bread; for you have brought us out into this wilderness to kill this whole assembly with hunger."

Then the Lord said to Moses, "I am going to rain bread from heaven for you, and each day the people shall go out and gather enough for that day. In that way I will test them, whether they will follow my instruction or not. On the sixth day, when they prepare what they bring in, it will be twice as much as they gather on other days." So Moses and Aaron said to all the Israelites, "In the evening you shall know that it was the Lord who brought you out of the land of Egypt, and in the morning you shall see the glory of the Lord, because he has heard your complaining against the Lord. For what are we, that you complain against us?" And Moses said, "When the Lord gives you meat to eat in the evening and your fill of bread in the morning, because the Lord has heard the complaining that you utter against him--what are we? Your complaining is not against us but against the Lord.'"

Then Moses said to Aaron, "Say to the whole congregation of the Israelites, 'Draw near to the Lord, for he has heard your complaining.'" And as Aaron spoke to the whole congregation of the Israelites, they looked towards the wilderness, and the glory of the Lord appeared in the cloud. The Lord spoke to Moses and said, "I have heard the complaining of the Israelites; say to them, 'At twilight you shall eat meat, and in the morning you shall have your fill of bread; then you shall know that I am the Lord your God.'"

In the evening quails came up and covered the camp; and in the morning there was a layer of dew around the camp. When the layer of dew lifted, there on the surface of the wilderness was a fine flaky substance, as fine as frost on the ground. When the Israelites saw it, they said to one another, "What is it?" For they did not know what it was. Moses said to them, "It is the bread that the Lord has given you to eat."

Psalm 105:1-6, 37-45

O give thanks to God,
   call on God's name,
make known God's deeds
   among the peoples.

Sing to God,
   sing praises to God;
tell of all God's wonderful works.

Glory in God's holy name;
   let the hearts of those
who seek God rejoice.

Seek God and God's strength;
   seek God's presence
continually.

Remember the wonderful works
   God has done,
God's miracles,
   and the judgments God uttered,

O offspring of God's servants
   Abraham and Sarah.
children of Jacob,
   God's chosen ones.

Then God brought Israel out
   with silver and gold,
and there was no one
   among their tribes
who stumbled.

Egypt was glad
   when they departed,
for dread of them had fallen
   upon Egypt.

God spread a cloud
   for a covering,
and fire to give light by night.

They asked,
   and God brought quails,
and gave them food from heaven
   in abundance.

God opened the rock,
   and water gushed out;
it flowed through the desert
   like a river.

For God remembered
   God's holy promise,
and Abraham and Sarah
   God's servants.

So God brought God's people out
   with joy,
God's chosen ones
   with singing.

God gave them the lands
   of the nations,
and they took possession
   of the wealth of the peoples,
that they might keep God's statutes
   and observe God's laws.
Praise be to God!

Jonah 3:10-4:11

When God saw what they did, how they turned from their evil ways, God changed his mind about the calamity that he had said he would bring upon them; and he did not do it.

But this was very displeasing to Jonah, and he became angry. He prayed to the Lord and said, "O Lord! Is not this what I said while I was still in my own country? That is why I fled to Tarshish at the beginning; for I knew that you are a gracious God and merciful, slow to anger, and abounding in steadfast love, and ready to relent from punishing. And now, O Lord, please take my life from me, for it is better for me to die than to live." And the Lord said, "Is it right for you to be angry?" Then Jonah went out of the city and sat down east of the city, and made a booth for himself there. He sat under it in the shade, waiting to see what would become of the city.

The Lord God appointed a bush, and made it come up over Jonah, to give shade over his head, to save him from his discomfort; so Jonah was very happy about the bush. But when dawn came up the next day, God appointed a worm that attacked the bush, so that it withered. When the sun rose, God prepared a sultry east wind, and the sun beat down on the head of Jonah so that he was faint and asked that he might die. He said, "It is better for me to die than to live."

But God said to Jonah, "Is it right for you to be angry about the bush?" And he said, "Yes, angry enough to die." Then the Lord said, "You are concerned about the bush, for which you did not labor and which you did not grow; it came into being in a night and perished in a night. And should I not be concerned about Nineveh, that great city, in which there are more than a hundred and twenty thousand people who do not know their right hand from their left, and also many animals?"

Psalm 145:1-8

I will extol you,
   my God and Ruler,
and bless your name
   forever and ever.

Every day I will bless you,
   and praise your name
forever and ever.

Great is God,
   and greatly to be praised;
God's greatness is unsearchable.

One generation shall laud your works
   to another,
and shall declare your mighty acts.

On the glorious splendor
   of your majesty,
and on your wondrous works,
   I will meditate.

The might of your awesome deeds
   shall be proclaimed,
and I will declare your greatness.

They shall celebrate the fame
   of your abundant goodness,
and shall sing aloud
   of your righteousness.

God is gracious and merciful,
   slow to anger
and abounding
   in steadfast love.

Philippians 1:21-30

For to me, living is Christ and dying is gain. If I am to live in the flesh, that means fruitful labor for me; and I do not know which I prefer. I am hard pressed between the two: my desire is to depart and be with Christ, for that is far better; but to remain in the flesh is more necessary for you. Since I am convinced of this, I know that I will remain and continue with all of you for your progress and joy in faith, so that I may share abundantly in your boasting in Christ Jesus when I come to you again.

Only, live your life in a manner worthy of the gospel of Christ, so that, whether I come and see you or am absent and hear about you, I will know that you are standing firm in one spirit, striving side by side with one mind for the faith of the gospel, and are in no way intimidated by your opponents. For them this is evidence of their destruction, but of your salvation. And this is God's doing. For he has graciously granted you the privilege not only of believing in Christ, but of suffering for him as well--since you are having the same struggle that you saw I had and now hear that I still have.
