There are many convictions that make me a Southern Baptist by choice, not by tradition. I firmly believe in believer’s baptism by immersion as practiced by Jesus himself. I firmly believe in the full inspiration of the Bible as God’s authoritative, inerrant Word. I firmly believe in the Gospel of Jesus Christ as the only means of salvation. For there is no other name under heaven by which men are saved (Acts 4:12). These convictions, among others, align me perfectly with my fellow Southern Baptist tribe.
Another HUGE conviction I have is that the Gospel of Jesus must go to all nations, to every people group, tribe and tongue. That we must pray for, support, and go as missionaries, spreading the Gospel in our Jerusalem, our Judea, our Samaria and to the ends of the earth (Acts 1:8). The missionary calling is for every believer. No one is exempt.
For those who have received the missionary call and are burdened by God to live and serve among another people group, they have my greatest respect. They are my heroes.
They are one of the main reasons I give my tithes and offerings to a Southern Baptist church which supports ministry in my city and state, and most importantly around the world through the Cooperative Program.
There is no other missionary sending agency on the planet that does domestic and international missions like Southern Baptists. We not only affirm and appoint over 10,000 missionaries, but we send them out with a full salary and ministry funds to do the work.
Every other missionary sending agency requires their missionaries to raise their own support and constantly make requests of their supporters back home. While I believe God has used this method greatly, I personally feel my tribe’s strategy is more focused and purposeful. It lets the missionary be a missionary and not focus so much on being a fundraiser.
We complete this strategy through giving to the Cooperative Program and through special missions offerings, namely the Lottie Moon Christmas Offering and the Annie Armstrong Easter Offering. For these offerings, every single penny goes straight to the mission field. Nothing is held back for administrative costs.
This is an investment that has an eternal impact seeing men and women, boys and girls from all corners of the world coming to Jesus Christ as Lord and Savior. That is an investment unlike any other.

I too am a Southern Baptist by choice not by tradition; although, I’ve been one long enough that the tradition is quite rooted. Where I connect with your statement is that coming on board as a Southern Baptist Christian I journeyed from outside (PCUSA, actually) the tribe.
