Never Give Up On Growing Up

23 Now may the God of peace himself sanctify you completely, and may your whole spirit and soul and body be kept blameless at the coming of our Lord Jesus Christ. 24 He who calls you is faithful; he will surely do it.

25 Brothers, pray for us.

26 Greet all the brothers with a holy kiss.

27 I put you under oath before the Lord to have this letter read to all the brothers.

28 The grace of our Lord Jesus Christ be with you. 1 Thessalonians 5:23-28 ESV

Like Peter and the other apostles, Paul had a strong expectation that the believers to whom he wrote would grow up in their salvation (1 Peter 2:2). Spiritual immaturity or stagnancy in their faith was unacceptable. He told the believers in Colossae that his preaching of Christ was intended to bring about salvation and sanctification.

Him we proclaim, warning everyone and teaching everyone with all wisdom, that we may present everyone mature in Christ. – Colossians 1:28 ESV

In his letter to the church in Ephesus, he told them that his responsibility as an apostle was to “to equip God’s people to do his work and build up the church, the body of Christ” (Ephesians 4:12 NLT). And then he added that this work of building up the body of Christ had a lofty end goal or objective:

This will continue until we all come to such unity in our faith and knowledge of God’s Son that we will be mature in the Lord, measuring up to the full and complete standard of Christ. – Ephesians 4:13 NLT

The work would never be done. Full spiritual maturity would never be achieved – at least, not in this lifetime. And Paul expressed to the Galatians his intention to keep pouring into them until they bore the likeness of Christ.

Oh, my dear children! I feel as if I’m going through labor pains for you again, and they will continue until Christ is fully developed in your lives. – Galatians 4:19 NLT

You might say that Paul was a man possessed. He could not bear the thought of any believer failing to experience the fulness of salvation offered to them in Jesus Christ. And this included their sanctification, the divine process by which believers are transformed into the likeness of Christ through the power of God’s indwelling Spirit.

So, as he begins to wrap up his letter to the believers in Thessalonica, Paul let’s them know of his desire for their holiness. It was his life’s passion and his constant prayer to God on their behalf.

Now may the God of peace himself make you completely holy… – 1 Thessalonians 5:23 NET

Paul knew that spiritual maturity was the work of God, not men. That does not mean we do not play a part, but that the work of sanctification is impossible without divine assistance. Paul has already told the Thessalonians that their sanctification was God’s will for them (1 Thessalonians 4:3), but now he reminds them that it is also God’s work. Only God can transform sinners into saints. Only He can replace their hearts of stone with hearts of flesh (Ezekiel 36:26).  Only He can radically alter their old natures, transforming them into new creations (2 Corinthians 5:17).

That is why Paul was constantly asking God to do what only He could do to bring about the spiritual maturity of His children.

I pray for you constantly, asking God, the glorious Father of our Lord Jesus Christ, to give you spiritual wisdom and insight so that you might grow in your knowledge of God. I pray that your hearts will be flooded with light so that you can understand the confident hope he has given to those he called—his holy people who are his rich and glorious inheritance. – Ephesians 1:16-18 NLT

Only God has the power to save and sanctify. And only God is capable of securing the spirits, souls, and bodies of His saints, so that they might remain “blameless until our Lord Jesus Christ comes again” (1 Thessalonians 5:23 NLT). By his use of the word “blameless,” Paul is not suggesting the possibility of achieving a state of sinless perfection in this life. He is simply reiterating a point he had made earlier in his letter. Their ability to one day stand before God “without fault” or “free from blame” would be the work of God.

May he…make your hearts strong, blameless, and holy as you stand before God our Father when our Lord Jesus comes again with all his holy people. – 1 Thessalonians 3:13 NLT

The ability to maintain a life marked by righteousness and holiness is a gift from God, just as salvation is. No one can save themselves and no one can preserve their saved state through self-effort. It is the work of God. And Paul assures the Thessalonians that God can be trusted to do what only He can do.

God will make this happen, for he who calls you is faithful. – 1 Thessalonians 5:24 NLT

God could be counted on to do His part. But they had a role to play as well. Paul has made that point perfectly clear throughout his letter. They would need to maintain their commitment to “serve the living and true God” (1 Thessalonians 1:9 ESV). They must continue to “walk in a manner worthy of God” (1 Thessalonians 2:12 ESV). He expected to hear that they were “standing fast in the Lord” (1 Thessalonians 3:8 ESV). And they could not afford to let up on their commitment to “live in holiness and honor—not in lustful passion like the pagans” (1 Thessalonians 4:4 ESV).

Their sanctification was a joint effort, powered by God, but requiring their willing and eager participation. If God’s will was their sanctification, they were going to have to adopt His will as their very own. It was essential that they make Christlikeness their primary passion and lifelong objective. And there was to be no goal less than full maturity in Christ. This meant that their sanctification would not be complete until they died and went to be with the Lord, or they lived long enough to see Him return at the Rapture for His church. Either way, the commitment to spiritual maturity and their ongoing transformation into the likeness of Christ was to remain their highest priority.

The apostle Peter reminds us that, because of our faith in Christ, we have been given all that we need to live godly lives. We lack nothing.

By his divine power, God has given us everything we need for living a godly life. We have received all of this by coming to know him, the one who called us to himself by means of his marvelous glory and excellence. And because of his glory and excellence, he has given us great and precious promises. These are the promises that enable you to share his divine nature and escape the world’s corruption caused by human desires. – 1 Peter 1:3-4 NLT

And the apostle John provides us with further assurance of our completed transformation into the likeness of Christ.

…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. – 1 John 3:2 NLT

Paul closes his letter with a request. He asks the Thessalonians for their prayers of intercession on the behalf of himself and the rest of his ministry partners. The work of sharing the Gospel required divine assistance. Paul coveted their prayer because he knew that he was in the midst of a spiritual battle “against evil rulers and authorities of the unseen world, against mighty powers in this dark world, and against evil spirits in the heavenly places” (Ephesians 6:12 NLT).

Finally, Paul asks that they express his love to all the members of the congregation and to make sure that his letter is read to everyone. And then he closes with a final blessing, asking that the grace of the Lord Jesus Christ be upon them. For Paul, the unmerited favor of God was a truly remarkable gift that never ceased to amaze and delight him. It was the key to salvation, sanctification and, ultimately, the glorification of all believers.
