To become a Christian, you need only believe in Christ and you will be saved (Acts 16:31). Being a Christian is not fundamentally about doing or earning. By all means, if you have questions about how to become a Christian, let me buy you a cup of coffee in Stillman Valley!
But understand. While one becomes a Christian through faith in Christ, and not by earning salvation, the faith that saves is a living faith. If you truly believe in Jesus, then you will be changed by the power of Christ.
Here is a great quote from the Westminster standards.
“Faith, thus receiving and resting on Christ and his righteousness, is the alone instrument of justification: yet it is not alone in the person justified, but is ever accompanied with all other saving graces, and is no dead faith, but worketh by love.” The Westminster Confession of Faith, 11.2.
