Because Christ has wiped all my sins ‘clean’ and removed all the handwriting that are against me, so shall we all do the same, if we believe in Him.

“having wiped out the handwriting of requirements that was against us, which was contrary to us. And He has taken it out of the way, having nailed it to the cross.”
(Colossians 2:14)

Try to understand the subsequent verse below:

“having disarmed principalities and powers, He made a public spectacle of them, triumphing over them in it.” (Colossians 2:15).

Ponder on Lord Jesus Himself with regards to how Great a Sacrifice He did at the Cross and How Great the result will be/is, to be testified in due times.

Indeed you can’t just “know Him” unless the Father Himself draws you to Him. And in return, the Son reveals Whom the Father is (full of Light) to whomever He wills. Indeed, God is love, as written by the apostle who leaned on Jesus’ breast and probably heard the very heartbeat of God Himself when He spoke this:

His words are not “death”, but they are “spirit” and they are “life”.

May all the world sing to You, “Jesus, Saviour of the World!”
