God chose Abraham. Genesis 15:7:
Notice that God informs Abraham and saves Lot not because of what they do, but simply because God has chosen them.
Lot has spent his years in Sodom as a righteous man. But it seems that he has tolerated - and even accommodated - the abominations of the society in which he dwells. Even though he has not succumbed to those vilenesses himself.
The nation who flouts the Lord is playing with fire. See Genesis 19:24 ff.
This should be a warning to our land today. Compromising God's word leads to disaster. Just as there are limits to God's patience, the should also be limits on our ability to tolerate and accommodate sin.
This is not to say that we ought to be judgmental. God alone will judge.
But we must, in all good conscience, point out destructive behaviors as outlined by scripture. When we fail to warn our society, we are guilty of aiding and abetting its sins.
Genesis 18:19: For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD... (KJV)
As children of God, we are expected to keep and teach the way of the Lord. When we keep only, we've fallen down on half of our job.
Give us the boldness to speak your words and righteousness. Help us to inform and teach with gentleness and love.
In Jesus' most precious name.
