The implication of our part being to believe on Jesus Christ and confess Him as risen Lord, is that He has done everything else! It is why we call it amazing Grace! It is why the gospel is nearly too good to be true!
Who raised Jesus from the dead? He raised Himself Joh 10:17,18 by His Holy Spirit Rom 8:11.
It is our personal confession of Jesus as mighty Creator and loving Saviour that seals that miracle.
We overcome by two actions and one attitude. The two actions; 1) Jesus shed blood 2) Our testimony.
The one attitude is 1) Being willing to die for Christ's sake.
Understanding this gives real meaning to this important verse which declares the power of salvation in the name of Jesus.
