One of the reasons that our worship runs against hellish fortresses on earth (think 2 Corinthians 10:3-5) is because God Himself has torn down the hellish ways of our own hearts. God saves sinners. God delivers us from the clutching, defensive power of sin.
The Father elected us for eternal life. The Son took on a body to be pierced for our transgressions and crushed for our iniquities. His Spirit He caused us to be born again to a living hope.
Think of the contrasts of His work in us. We who were far off He has brought near. We who were dead He has raised to walk in newness of life. We were rebels that He adopted as sons. We were at enmity with us and He reconciled us. We did not believe and He granted repentance in order that we might have a knowledge of the truth. We were not humble, we deserved to be opposed by Him, but now He promises to exalt us with Himself in glory.
He broke down the wall. He softened the hard. He illuminated the dark.
Christ also suffered once for sins, the righteous for the unrighteous, that he might bring us to God (1 Peter 3:18)
What a day for rejoicing.
