'Who also will do it' signifies God's commitment to fulfill His promises and execute His plans for His people.
The phrase 'who also will do it' in 1 Thessalonians 5:24 reassures believers that God not only calls them but also ensures the completion of His promises and purposes in their lives. This reflects the assurance that God is actively working in believers, guiding and enabling them to fulfill their calling. God's faithfulness assures us that He does not leave His work undone; rather, He is intimately involved in the sanctification and glorification of His people. Throughout biblical narratives, we see this theme manifest, as God was faithful to His promises to figures like Abraham, Moses, and Paul, demonstrating that He will certainly carry out His plans and intentions for His people now and into eternity.
