Proverbs 5:9 Or you will give your vigor to others And your years to the cruel one;
This verse is in the midst of verses that talk about immorality, when we do not seek to follow God, this is what will happen to us. As I have said before, if we are not following God, then we are following someone else. This verse tells us who, the cruel one and yes that would be Satan. When we do not walk and talk with God and keep our focus on Him, the cruel one will creep in and take over out thoughts and tempt us to give in to our desires. We must guard against it and stay in God's Word!
