Some wrongly teach or assume that salvation guarantees favorable circumstances in this life. However, the Bible makes no such guarantees. In fact, what the Bible does guarantee for the follower of Jesus is tribulation (John 16:33), trial (James 1:2), and persecution (2 Tim. 3:12). And yet, the ultimate promise of the gospel far outweighs any of these temporal realities.
In the words of the Apostle Paul, for the believer enduring such realities, “this light momentary affliction is preparing for us an eternal weight of glory beyond comparison, as we look not to the things that are seen but to the things that are unseen” (2 Cor. 4:17-18). Thus, the gospel-centered life—the truly “successful” Christian life—is a life lived in faith toward Christ, in view of the eternal not the temporal.
