Gen 19:36-38 Thus both the daughters of Lot were with child by their father. 37 The firstborn bore a son and called his name Moab; he is the father of the Moabites to this day. 38 And the younger, she also bore a son and called his name Ben-Ammi; he is the father of the people of Ammon to this day.
Another thing that we can learn from Lot based on this temporal blessing is what he left behind after his life. The descendants of Lot are Moab and Ammon. Both went away from God and had their own abominations of idols. They were always at war with Israel. Likewise, these temporal blessing sometimes leads us knowingly or unknowingly to defilement and finally an abomination before our Lord God. These blessings will slowly move us away from the Way of the LORD and make us to put a stumbling block for our generations to come. We can see now in our lifetime how a nation full of God can slowly turn into an abomination before God after some generations. This is happening even today because one generation fail to seek the true blessing of the Lord and that error slowly flows into next and finally it goes down in the wrong path altogether. If we truly seek the eternal blessing of God according to His providence plan, then our generations will be blessed in Christ Jesus our Lord. If we seek the temporal blessing then we could set a stumbling block for our children.
