Meaning CHRIST has ACCOMPLISHED what GOD had sent him here to BRING TO an END Christ COMPLETED His Mission!! Jesus completed this Mission by his Death and Resurrection on the Cross. The Finished Work of God. How did he achieve this work God sent him here to do? By destroying the work of Satan. Satan's work is he brought in Sin, which separated us from God. And the scripture says Christ came to destroy Satan's work (1 John 3:8). He did this by sacrificing his Blood on the Cross, in which the scriptures state, "e;The Blood of Jesus Wipes Out All Sin"e;(1 John 1:7)-Thereby connecting us back to God.
