21. God accepts us on the basis of faith in our hearts (Gen.4:4-5). God had regard for Abel first and therefore for his offering. He came with faith proved by the fact that he brought the best; whereas, Cain only brought just "an" offering. A man of faith always gives the very best of his life and everything to God

22. Beware of anger and jealousy (4:5-6). God asked Cain "Why are you angry? Why is your face fallen?" He will ask us the same questions. Jealousy destroyed Cain. It also destroyed King Saul when he saw David's popularity.

23. Sin is closer to us than we think (4:7). Sin is always crouching like a lion or tiger at the door of our hearts just waiting to enter. If we always recognize that sin is so close to us, we will always be alert.

24. God wants us to be overcomers (4:7). God wants us to master sin. He told Cain that, long before the Holy Spirit was given to man. External sins can be conquered even without the help of the Holy Spirit. But inward sins can be conquered only through the power of the Holy Spirit.

25. We are responsible for our fellow-believers (4:9). If our left hand is injured, our right hand immediately helps to fix it. In the Body of Christ, if one member suffers, all suffer. If one member rejoices, all rejoice. In a football game, all will rejoice even if someone else from their team scored the goal, because he is part of the same team. We are responsible for those we are closely connected with, in our local churches.

26. We have to give an account to God for everything we have done (4:10). The harm we do to others cries out to God. No one may have seen our sin. But God will ask us to account for it. That is why we need to be honest and confess all our sins to God - and especially the sins done in secret. We must do it now, before we meet God one day.

27. Sins against another are more serious than sins that harm only yourself (4:11). God never cursed Adam for his sin, but only the ground, because Adam's sin hurt only himself. But God cursed Cain. A person who has bad habits like taking drugs and alcohol is harming only his own body. But one who backbites or expresses his anger harms others; and so he is worse than a drug-addict. But hardly anyone believes that.

28. We will reap what we sow (4:12). Cain was punished to become a wanderer, because of his sin. Many Christians too are homeless wanderers, never getting integrated into any local church as their home. They are too independent to be subject to anyone's authority. That is part of a curse. And the root cause for this is only their pride.

29. Vengeance belongs to God alone (4:15). We must never take revenge on anyone (Romans 12:19). Let God repay all evildoers in His own way and in His own time.Our calling is to overcome evil by doing good. Paul had been harmed by Alexander; but he left it to the Lord to deal with Alexander (2 Tim.4:14).

30. Our children will follow our example. Cain killed Abel. Cain's descendant, Lamech, killed others. When parents go astray, their children go astray. Another descendant of Cain's - Jubal - was the father of the musical industry. He was certainly not glorifying God with his music, but glorifying Satan - just like the rock musicians of today. Our children and grandchildren will follow our example. So we should walk in humility and brokenness always.
