Why is it essential for Christians to trust in Christ alone?

For Christians, faith in Christ alone is fundamental because He is the only Savior capable of delivering us from sin and its consequences. As stated in Acts 4:12, there is no other name under heaven by which we must be saved. This underscores that reliance on our works, rituals, or any other form of righteousness will ultimately prove to be in vain, akin to wood, hay, and stubble that will be burned up. The gospel teaches us that it is God who saves, and faith is a gift that leads believers to acknowledge their need for Christ, ensuring that their hope rests solely on His completed work. This reliance leads to true spiritual life and transforms our relationship with God, as it solidifies our identity as His children through faith in Christ.
