In today’s religious world, Christian Baptism is often misunderstood and sometimes downright disrespected. This God-given instrument gives or strengthens saving faith in Christ, but too often it becomes a mere human act of obedience or a mere external sign. But is it possible that people sometimes give Baptism too much credit? Your question makes me think of that possibility. Are the blessings of Baptism overstated when we speak of it “guaranteeing faith and eternal salvation”?

Baptism gives saving faith

Paul assured the Galatians, “All of you who were baptized into Christ have clothed yourselves with Christ” (Galatians 3:27). In and through Baptism, a most intimate link between the sinner and the Savior is promised and accomplished.

Other New Testament passages affirm that the gifts of the Holy Spirit, forgiveness of sins and salvation, are bestowed through Baptism. They are not just symbolized or pictured in Baptism. Baptism gives these blessings. Perhaps because of such vigorous promises, people speak of Baptism “guaranteeing” salvation. But more needs to be said.

Saving faith needs gospel nourishment

If the baptized sinner retains saving faith, he or she will retain the gift of salvation and inherit heaven. But this is different than saying that Baptism guarantees heaven. Baptism is God’s way of beginning or enriching a lifelong relationship, but it remains vital that the faith given be nurtured and strengthened through the gospel aside from Baptism. This is why, when children are baptized, we urge parents and others to include the children in family devotions, train them to read Scripture at home, and have them participate in public worship and Sunday school.

It is important that all who are baptized enjoy growth in faith to maintain their hold on God’s salvation promises. If the saving faith received through Baptism is allowed to die, it will result in the forfeit of spiritual and eternal life. It is irresponsible to speak of Baptism “guaranteeing” salvation unless this kind of clarification is immediately added. God has chosen to give and preserve faith through the means of grace, that is, the gospel in Word and sacraments. After Baptism, to despise the Word and the Lord’s Supper is more like guaranteeing eternal death, not life.
