1. Do not murder (21-22)
Human life is precious because man is created in God's image. Giving and taking life is something that only God has the right to do, for life belongs to him. Here, Jesus teaches that 'Do not murder' touches the thoughts of our hearts. It means that we must not hate others or hold grudges. To give way to anger is like murder. And if we let our anger erupt in harsh and insulting words, we are in danger of going to hell.
2. Be reconciled (23-26)
Not only am I responsible for my own feelings toward my brother, but I am responsible also for his feelings toward me. If, while I am offering a gift to God, I remember that my brother has something against me, I must first go and do all I can to be reconciled with him. Even in worldly relationships, it is wise to be reconciled with anyone who is an adversary. How much more important it is to be reconciled to God!
Application: Lord, thank you for Jesus whose shed blood reconciles me to you. Cleanse anger and self-pity from my heart and give me faith to be reconciled to all others.
One Word: First be reconciled
