“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. He who calls you is faithful; he will surely do it.” 1 Thessalonians 5:23-24
How good is this verse of Scripture. It is the benediction given by Paul to the church at Thessalonica. Note: God is the One who will sanctify you and cause you to mature into the image of Christ. It does take work on your part, which is detailed in the preceding verses.
“Rejoice always, pray without ceasing, give thanks in all circumstances; for this is the will of God in Christ Jesus for you. Do not quench the Spirit. Do not despise prophecies, but test everything; hold fast what is good. Abstain from every form of evil.” 1 Thessalonians 5:16-22
Thankfully, God, the Holy Spirit is the source and strength of our progress. One day you’ll be completely whole, perfect, and pleasing to God in every way. This will happen at the Second Coming of our Lord Jesus Christ. Until then, we are works in progress.
