Understand Once For All Forgiveness, and You Forgive Others

"And be ye kind one to another __ tenderhearted forgiving one another even as __ God for Christ's sake hath [fully and forever, once and for all] forgiven you" (Ephesians 4: 32)

"fully and forever, once and for all"  cannot be emphasized enough.

"Hath forgiven" renders the aorist tense from the original Greek, which speaks of an action which has been completed, fully and without need of repetition.

The greater our understanding that Jesus Christ has done it all, taken care of our sin, our righteousness, our healing, our wealth, and every other need, to that extent we can present and actively forgive others.

This forgiveness of sins opens up His storehouse of blessings into our lives, because we receive Christ's righteousness (1 Corinthians 1: 30; 2 Corinthians 5: 21)

"Blessings are upon the head of the just: but violence covereth the mouth of the wicked." (Proverbs 10: 6)

and

"I have been young, and now am old; yet have I not seen the righteous forsaken, nor his seed begging bread." (Psalm 37: 25)

and

"His seed shall be mighty upon earth: the generation of the upright shall be blessed." (Psalm 112: 2)

and

"14In righteousness shalt thou be established: thou shalt be far from oppression; for thou shalt not fear: and from terror; for it shall not come near thee." (Isaiah 54: 14)

and

"
17No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the LORD, and their righteousness is of me, saith the LORD." (Isaiah 54: 17)

Our righteousness is from the Lord through His Son!

We receive this and every other blessing because we are forgiven, and we are forgiven because Jesus Christ has paid the full price for all of our sins (Colossians 2: 13-15).
