Water baptism has always been an Israel thing and there are references to it in the OT. Everyone in the Bible that was water baptized was either a Jew or was a saved Gentile during the Acts period, all of whom were part of Israel, since they were all grafted into Israel.
We today are not a part of Israel in any imaginable way. In fact, there is no Israel today, in God's eyes, and hasn't been for 1954 years. They will be back as God's people shortly though, in about 2064. We Gentiles are God's chosen people today. The only place you'll find our marching orders for today and what our exact future will bring is in Paul's 7 epistles written AFTER Acts. Water baptism isn't mentioned in those 7 ALL-GENTILE books. If it doesn't specifically say so in those 7 books, it doesn't belong to you. The other 59 books are totally for Israel. Except for Christ, nothing EVER given to Israel was also given to the Gentiles.
Here's a few things that were NEVER, EVER given to you. There are 100s more that the Denominational Church System has stolen from Israel. It really makes no difference, though. Since none of these things were ever given to you, you'll never get them anyway. Go to Paul's last 7 books and see what REALLY belongs to you. Heaven, for example, which no Jew (except Christ) EVER had a chance of going to. Search and See!! Millions of times better than anything ever given to Israel.
These things don't belong to you, or me or anyone, Jew or Gentile, saved after about 64AD. Different people. Different Times. Different Dispensation.
