Most of the world is made up of vengeance, getting even, gaining prestige, and much worse. Jesus looked over the city of Jerusalem, which crucified Him for teaching the truth, healing the sick, and raising the dead.
This alone matters - knowledge and love for Jesus, the Son of God, the Savior and Teacher of all. Much is said about forgiveness, which is good, but too little is said about the Faith of Jesus which gains access to His grace. Lacking faith, there is no grace, or only a hint.
My addicted friends know all about their sinfulness. They have lived the life of repeating mistakes and wrecks, promising to stop... on the way out of the hospitals... hoping for detox.
The central theme of the Bible is Jesus as Love. That is central and necessary because love and fear are opposites. Love subdues the fear within us, and that love increases confidence (con-fidence means "with faith.")
Someone can be haughty and arrogant, knowing and doing all things to impress themselves and others. But when the truth of Jesus' love is discovered from within, he is crushed by the vacuum of knowing and experiencing so little from the Redeemer.
