Genesis 19:16 When he hesitated, the men grasped his hand and the hands of his wife and two daughters and led them safely out of the city for the Lord was merciful to them.
Speaking of Lot and his family before Sodom and Gomorrah were going to be destroyed. The angels urged Lot saying "Hurry, take your wife and your two daughters who are here or you will be swept away when the city is punished." (Genesis 19:15)
Direct warning/statement of what was going to happen if they stayed and Lot hesitated. He should have jumped at the chance to be out of there in a "heartbeat," but he had to be taken by the hand and led out. His sons-in-law pledged to his daughters thought he was joking when he told them to leave. (Genesis 19:14)
Lot had too much of the world in him. He was not sensitive, aware of God's voice speaking to him, advising him what to do. He liked the security of where he was (even though it was a wicked environment).
Was God merciful to Lot because Lot was related to Abraham (Abraham's nephew). Could be. Genesis 19:29 says "so when God destroyed the cities of the plain, he remembered Abraham and brought Lot out of the catastrophe that overthrew the cities where Lot had lived."
Lot had strayed or perhaps Lot never had the commitment to follow the God (True God) that Abraham followed. He chose the world and the world let him down. Abraham chose God and even though Abraham had his moments of falling away from obeying God, he still chose God over the world. God did not let him down. God was faithful and kept all promises made to Abraham.
Each of us can choose who we will follow, who will we listen to. Choose wisely for the Only One who will never let you down . He never has let me down and he never will.
Thank you Lord for your faithfulness.
