15 And He said to them, “Go into all the world and preach the gospel to every creature. 16 He who believes and is baptized will be saved; but he who does not believe will be condemned.” (Mark 16:15–16, NKJV)
This passage is not difficult to understand. Yet, it undergoes no end of abuse at the hands of those who refuse its teaching on how the gospel saves sinners. Christ’s commission to the apostles is forthright: “Go into all the world and preach the gospel to every creature” (v. 15). The gospel is for all, and the apostles made known its power to save “to all nations” (Rom. 1:16; 16:25-26; Col. 1:23). Responses to the gospel and their corresponding results are stated candidly in verse 16. The person who believes the gospel and is baptized will be saved from sin, but the person who does not believe the gospel will be condemned in sin. Believing the gospel of Christ compels one to be baptized to be saved. Yet, controversy arises over whether water baptism is necessary for salvation. Jesus said it is. Why? Because “faith by itself, if it does not have works, is dead” and cannot justify the sinner (Jas. 2:17, 24). Water baptism is faith at work as one submissively obeys Christ’s command (Acts 2:37-38; 10:34-35). Obedient faith does not earn salvation (Lk. 17:10). When the believer obeys the gospel, God frees that person from sin’s bondage to become a slave of righteousness (Rom. 6:17-18). Belief and baptism are essential to be saved. Unbelief is condemned. Instead of arguing with Jesus, we plead with the lost to believe and be baptized to be saved.
