"As far as the east is from the west, so far hath he removed our transgressions from us." (Psalm 103: 12)
How far is east from west?
The more that you try to determine it, the farther East and West become.
In the same manner, God invites to grow in grace and knowledge of the Lord Jesus.
The more that we understand how gracious Jesus is, we then realize that He exceeds in grace to us:
"20Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us, 21Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen." (Ephesians 3: 20-21)
"Exceeding abundantly" Paul writes to the Ephesians. To the Romans, He writes:
"31What shall we then say to these things? If God be for us, who can be against us? 32He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?" (Romans 8: 31-32)
"37Nay, in all these things we are more than conquerors through him that loved us. 38For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, 39Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord." (Romans 8: 37-39)
Our sins are being forgiven, and forever.
We receive this overwhelming victory as we grow in understanding of how great is this forgiveness.
Whatever you did in the past, not only has God already forgiven your sin, but He is taking that evil and turning it to your good:
"28And we know that all things work together for good to them that love God, to them who are the called according to his purpose. 29For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren. 30Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified." (Romans 8: 28-30)
John could not make it clearer:
"7But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin." (1 John 1: 7)
"1My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: 2And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world." (John 2: 1-2)
Even now, you have an advocate and an intercessor who is ministering for you, that you are always being forgiven, forever: Jesus!
