2 Timothy 2:11-12 (KJV) (11) It is a faithful saying: For if we be dead with him, we shall also live with him: (12) If we suffer, we shall also reign with him: if we deny him, he also will deny us:
Jesus died as our substitute on the cross. Our faith in what He did, places us there on the cross with Him. Since we are dead with Him, we will live in Eternity with Him. This will happen when we receive our resurrection body. We were planted together with Jesus in death, and it was all done at the Cross of Calvary.
(Read 1 Timothy 1:15)
