You only need to trust Christ to be saved.

Is trust in Christ all that's needed to be saved? Is mental assent and agreement to what you've deduced from listening to a preacher going to do it? “Just trust in Christ,” most denominations proclaim, “and you're saved.” “Lay your hand on the radio and repeat after me!” Done that. “Kneel with me and recite the Sinner's Prayer.” Been there—about twenty times. According to the Billy Graham Evangelistic Association, the founder is credited with preaching the gospel to 215 million people. However, after walking the aisle to mutter the “Sinner's Prayer,” none followed up by attaching themselves to a church family, and only 2 percent remained faithful to their decision.1

Salvation is not some drive-through window affair. God is not a short-order cook, answering your call to a 30-second prayer. Nor is it praying the Sinner’s Prayer (a recipe found nowhere in scripture) and you're saved. Salvation is deadly serious business.

Trust (faith) in Christ is the first step toward salvation. However, repentance is also part of the process, where you determine to change your life's direction. (Luke 13:3; Acts 2:38; 17:30) Confession of your faith is also mentioned. (Matt 10:32; Rom 10:9) Baptism is the final step, where you submit your body for burial in water.2 (Acts 2:38; Rom 6:1-4; Gal. 2:20; 1 Pet 3:21) Thus, mind, spirit and body all submit. Once these four conditions have been met, you're then justified before God—no longer guilty of sin. (Rom. 3:23-24) The process of sanctification—a life-long process—then commences, re-shaping and molding you into Jesus' image. (Rom. 8:29)
