God teaches that we must keep his commandments to enter His kingdom(Matthew 7:21). Baptism is a commandment(Matthew 28:19). Therefore, how can we be in His kingdom if we are not baptized?
It is not about a percentage of passages that teach one thing or another. If something is taught in the Word of God and you don't abide by it, that is not doing His Will. How many times does God have to tell you something before you accept it?
God is not a liar. At the same time, you can't pick and choose which passages to believe. I believe all those passages that don't mention baptism, and I believe all the passages that do teach baptism. That is because the Word of God is truth. You have to take His Word as a whole, not in part. Taken as a whole, we are taught to believe, repent, confess, and be baptized.
So then you are not saved by grace or mercy, but because you keep the law?
