The nature of our salvation requires us to live in the present while simultaneously looking backward to the past and forward to the future. We keep in mind the once for all finished work of Christ by which he actually completed our salvation. When he said, “It is finished,” he meant it. Nothing can be added to or subtracted from what he accomplished. It simply must be believed and received by faith, a faith that includes our faithful allegiance to him as Lord. This is the basis of our ability to rest in God’s grace. The immediate beneficiary of Christ’s perfect work is the innermost part of us – the Spirit, where we are born again and made righteous. This is where God dwells inside us. We are united to God’s Spirit through the miracle of justification.
But our High Priest offered himself to God as a single sacrifice for sins, good for all time. Then he sat down in the place of honor at God’s right hand. 13 There he waits until his enemies are humbled and made a footstool under his feet. 14 For by that one offering he forever made perfect those who are being made holy. Hebrews 10:12-14 (NLT)
Dear friends, we are already God’s children, but he has not yet shown us what we will be like when Christ appears. But we do know that we will be like him, for we will see him as he really is. 3 And all who have this eager expectation will keep themselves pure, just as he is pure. 1 John 3:2-3 (NLT)
We live in a divine tension between the past, present, and future. Those who are already made perfect in spirit are being made holy in the soul while awaiting the resurrection of the body. This is a tension between the already done bumping into that which is still in process and waiting completion.
The ongoing work of the Spirit is firmly rooted in the already finished work of Christ. God is working out in time what has been settled for eternity.
The Spirit is God’s guarantee that he will give us the inheritance he promised and that he has purchased us to be his own people. He did this so we would praise and glorify him. Ephesians 1:14 (NLT)
