The One on whom we wait is a dissatisfied Messiah. He will not relent, he will not quit, he will not rest until ever promise he has made been fully delivered. He will not turn from his work until every one of his children has been totally transformed. He will continue to fight until the last enemy is under his feet. He will reign until his kingdom has fully come. As long as sin exists, he will shower us with forgiving, empowering, and delivering grace. He will defend us against attack and attack the enemy on our behalf. He will be faithful to convict, rebuke, encourage, and comfort. He will continue to open the warehouse of his wisdom and unfold for us the glorious mysteries of his truth. He will stand with us through the darkness and the light. He will guide us on a path we could never have discovered or would never have been wise enough to choose.
John Piper: There is a faith-sustained holiness that Paul wants his converts to have on the day of Christ — the day of his return, when the dead in Christ will be raised (1 Corinthians 15:23). This holiness (which he also calls “blamelessness” and “guiltlessness” and “being above reproach” and “purity”) is certain through God’s faithfulness, contingent on persevering faith, and dependent on human agency. Certainty Paul is certain that God will work this persevering faith and holiness in his converts for the day of Christ. This is part of God’s faithfulness.

He who calls you is faithful; he will surely do it. (1 Thessalonians 5:23–24) You wait for the revealing of our Lord Jesus Christ, who will sustain you to the end, guiltless in the day of our Lord Jesus Christ. God is faithful, by
“When we take the history of a child of God, compressed within the short period of a single day — mark what flaws, what imperfections, what fickleness, what dereliction in principle, what flaws in practice, what errors in judgment and what wanderings of heart make up that brief history — how we are led to thank God for the stability of the covenant, that covenant which provides for the full redemption of all believers, which from eternity secures the effectual calling, the perfect keeping and certain salvation of every chosen vessel of mercy!” Octavius Winslow, Personal Declension and Revival of Religion in the Soul (London, 1962), page 169.

I will put My fear in their hearts—so they will never turn away from Me. (Jer 32:40) Jesus, to whom I have been led to commit myself, has engaged to save me, absolutely, and from first to last. He has promised not only that He will not depart from me—but that He will put, keep, and maintain His fear in my heart—so that I shall never finally depart from Him! And if He does not do this for me—I have no security against my turning apostate! For I am so weak, inconsistent, and sinful; I am so encompassed with deadly snares from the world; and I am so liable to such assaults from the subtlety, vigilance, and power of Satan—that, unless I am ‘kept by the power of God,’ I am sure I cannot endure to the end!
