We continue to sin and fail ... we have not repented enough ... we are too weak to hold onto Christ ..." the list of failures that Satan casts in front of us goes on and on.
But we thank God that our salvation ... our redemption ... is not based on us ... but on Jesus Christ ... Here is a wonderful message from Charles Spurgeon on "Looking to Jesus"
“Christ is all in all.” Remember, therefore, it is not your hold of Christ that saves you—it is Christ; it is not your joy in Christ that saves thee—it is Christ; it is not even your faith in Christ, although that is the instrument of salvation— but it is Christ’s blood and sacrifice that saves; therefore, don't look to your hand with which you are holding onto Christ, look to Christ ... look not to your hope, but to the hope in Jesus, the source of your hope ... look not to your faith, but to Jesus, the author and finisher of your faith. We shall never find happiness by looking at our prayers, our doings, or our feelings; it is what Jesus is, not what we are, that gives rest to the soul
Hebrews 12: 2
Looking to Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.
