I think that is basically all. Water baptism. Dispensationalists see it as part of God’s program under the Dispensation of the Law, like circumcision. And if water baptism were required in this dispensation of grace, there would be 2 baptisms, not the one that Paul described in Eph. 4:4-6.
I guess I can’t speak for all Baptists, by I, as a Fundamental Independent Baptist (our church is not bound to a convention, association, or hierarchy) was taught to trust in nothing for salvation but the death, burial, and resurrection of Jesus Christ.
Soon after, I was shown Scripture about baptism. I was specifically shown it was NOT necessary for salvation (the thief on the cross next to Jesus wasn’t baptized), but was shown that if I gladly received Christ as Saviour (Acts 2:41) and that if I believed with all my heart (Acts 8:37), I should get baptized.
Essentially, I was taught that baptism (immersion) was something you did outwardly to show the inward decision you made in your heart to trust Christ—as opposed to being sprinkled as a baby as payment for sin.
The Christ that was hung on the cross, buried for three days, and risen again did that for me! I’m trusting him and no one else.
