Because God alone is judge.
Ps 103:6 The LORD executes righteousness and justice for all who are oppressed.
Romans 12:19 Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, “Vengeance is Mine, I will repay,” says the Lord.
Heb 10:30 For we know Him who said, “Vengeance is Mine, I will repay,” says the Lord. And again, “The Lord will judge His people.”
Ps 19:6b The judgments of the LORD are true and righteous altogether.
Luke 6:37 Do not judge, and you will not be judged. Do not condemn, and you will not be condemned.
Because God ultimately will judge.
Exodus 34:7 keeping mercy for thousands, forgiving iniquity and transgression and sin, by no means clearing the guilty,
Because it is for our benefits.
Luke 6:37 “Judge not, and you shall not be judged. Condemn not, and you shall not be condemned. Forgive, and you will be forgiven.
Matt 6:14 For if you forgive other people when they sin against you, your heavenly Father will also forgive you. But if you do not forgive others their sins, your Father will not forgive your sins
Because we fall into the same condemnation .. we too have sinned and offended and hurt people.
Because we are incapable of executing justice universally and fairly to all – punishing all who had made the same offense .
Because with unforgiveness we are punishing ourselves for the hurt we are inflicted with by others
Because unforgiveness consumes us and eat us up alive inside and affects our health.
Because God extended grace to us and wants us to extend the same grace we received to others.
Because when we judge others we fall into the same judgment we judge others.
Because we are incapable of rendering true justice.
Because only God knows and sees all things, we don’t.
Because the only person that suffers is you.
Bottom line … God says so. Trusting that God knows what He said and does.
Colossians 3:13 Bear with each other and forgive whatever grievances you may have against one another.
