“I was baptized many years ago and I need to be sure that I knew enough. I knew I had to be baptized so I could be saved and that baptism would put me into the church of Christ. But that is all I knew about the purpose of baptism. Was that enough?”
You are not alone. Many people (years after their conversion) question whether they “knew enough” when they were baptized. But look again at what you knew, and then reread Acts 2:37 – 47. When the people in Jerusalem realized they were lost, they were told, “Repent, and each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the Holy Spirit” (verse 38, New American Standard Bible). They did that (Acts 2:41) and the Lord added them to the church (verse 47). How much did they know? They knew they were lost, they were told what to do to be saved, they did it and the Lord added them to the Lord’s church. They knew enough.
According to your question, you knew the same thing they did, you did the same as they did, and the Lord – according to His promise – saved you from sin and added you to His church. You knew enough.
In the years since your baptism, you have grown in faith and knowledge. That is natural and God expects if of you. But that doesn’t mean you didn’t know enough when you were baptized. It simply means you became a baby (or an infant) in Christ (I Corinthians 3:1) when you were baptized into Christ. You were then to “grow up in all aspects into Him who is the head, even Christ” (Ephesians 4:15). Evidently, you are doing that. Keep growing. But never question the Lord (nor His power) to keep you in fellowship with Him.
