If we are to follow all Scripture without Scripture weighting, we understand that what saves you eternally is not simply one thing. It’s not grace3 (alone). It’s not faith1,2 (alone). It’s not baptism5 (alone). It’s all of these and more4,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20!! If “The sum of your word is truth” (Psalms 119:160), then all of these must have a part in what saves you. Likewise, if any single part is missing, then you are not saved.
Yes, what saves you eternally is all made possible and starts with God’s grace3. Specifically, the gift of His Son1,17,18,19. However, that gift can be accepted (or rejected) by belief2,4,12,18,19 in Him. We also see the necessity for obedience to His word1,2,3,6,8,9,11,12,13,14,15,16,17. We see the working/setting apart by the Holy Spirit7,8,13,14. We also repeatedly see the critical role that baptism plays5,15. By the way, it’s never presented as anything optional or ceremonial. Along with belief and confession2 with an open heart10, it is one of the very first acts of obedience4,7,8,15. Just as Paul emphasizes grace in one passage3, Peter (and Jesus15) emphasizes baptism in another5.
God has made provision for our salvation1,2,3,6,7,8,10,14,16,17,18 to all the world; things we can only understand from His word2,9,10,11,13,16. It’s up to each of us to respond1,2,3,4,5,6,8,9,10,11,13,14,15,16,18,19 and remain faithful until the end20.
