For this reason we also thank God without ceasing, because when you received the word of God which you heard from us, you welcomed it not as the word of men, but as it is in truth, the word of God, which also effectively works in you who believe (1 Thessalonians 2:13, NKJV).
Paul unashamedly declared the gospel of Christ “is the power of God to salvation for everyone who believes” (Rom. 1:16). The gospel’s power to save the lost reached Thessalonica, where Paul, Silas, and Timothy preached “the gospel of God in much conflict” (1 Thess. 2:1-2; Acts 17:1-9). How the Thessalonians “received the word of God” (1 Thess. 2:13) is how the gospel’s power continues to save lost souls. (1) First, the lost person must hear the word of God. The gospel cannot save if the sinner does not hear it (Rom. 10:13-17). The Thessalonians heard God’s word (v. 13). (2) Second, the lost person who hears the word of God must believe it. The gospel cannot save if the sinner does not believe it is true. The Thessalonians “welcomed” what they heard from Paul, Silas, and Timothy as God’s word, not man’s (v. 13). The gospel they preached is still the truth one must believe for salvation. (3) Third, the lost person must be converted and obey the word of God (Acts 3:19; 2:38). The gospel cannot save if the sinner does not obey it. Obedient faith saves. Otherwise, it is dead faith (James 2:17-18). When the Thessalonians heard, believed, and obeyed the gospel, they turned from idols to serve the living and true God (1 Thess. 1:8-9). The word of God “effectively works in you who believe” (Christians, v. 13). Hear, believe, and obey the gospel, and its power will work in your life, too (Phil. 2:12-13).
