Genesis 18:1-33 "Is anything too hard for the Lord?" (Genesis 18:14). God was intent on doing something great - "through him (Abraham) all the nations of the earth will be blessed" (Genesis 18:18) - and nothing was going to stop Him. Even if a great many people - Sodom and Gomorrah - refused to honour God, His purpose would not be hindered. He would find a remnant for Himself. the remnant may have seemed impossibly small, but it was to be the beginning of blessing for all the nations. the smallness of the beginnings serves to emphasize the greatness of the blessings. This is not man's doing. It is the work of God, and all the glory belongs to Him, the god of salvation, the God of grace, the God of glory.
Genesis 13:1-18 The life of God's people - those who worship Him (Genesis 13:4) - is always set in the context of wickedness. There are always choices to be made. Like Abraham, we can choose to worship God, or we can be like Lot and choose to go the way of wickedness. The choices we make reveal the people that we are. Those who choose the way upon which the Lord's blessing rests show that their hearts belong to the Lord. Those who choose the way upon which the Lord's judgment rests show that their hearts belong to the world. the worldly man, Lot, thought only of himself. The spiritual man, Abraham, concerned himself with doing the Lord's will. There is a great difference between Lot and Abraham - "Lot chose the whole Jordan plain for himself"; "The Lord said to Abraham... 'I will give you all the land you see to you'" (Genesis 13:11,15). The worldly man takes for himself. The spiritual man waits to receive from God.
