Welcome to the forum, Jennifer! May God grant you wisdom as you learn of His Holy Church!
HabteSelassie frames this situation very well. I have to agree with all he has said.
I, too, was originally a Baptist. I responded to an altar call at the age of eight in my Missionary Baptist (that's outside the SBC
) church in Southeastern Kentucky. I was baptized the very next Sunday. The altar call was particularly impressionable on me. I had spoke to the preacher the Sunday before about how to accept Jesus, and he instructed me to respond to the altar call next Sunday. I did so, and knelt at the step in front of the platform at the front of the church (of course, this is what the Baptists call an "altar"). I prayed in my own lil' eight-year-old heart, and felt the hands of the preacher on me as I did so. Many other church elders also laid their hands on me. I remember crying. It was a very emotional experience for me, and I do believe I experienced the Holy Spirit at that moment for the first time. the baptism I received the next Sunday was also very important to me.
I wondered around various Protestant denominations once I got older, looking for the truth. Immediately before I made the jump into Orthodoxy I was a Presbyterian who had strong leanings towards Anglo-Catholicism. Not nearly as emotionally-driven as that original Baptist upbringing. That said, when I converted to Orthodoxy, I was baptized and chrismated. I had a very similar feeling at that time to when I was eight, but it wasn't exactly the same. I didn't shed a tear, and didn't stay or even think much of anything. The biggest impressions left on me is how joyfully I recited the Nicene Creed, knowing I was finally confessing the True Orthodox Faith of the One Holy Catholic Church. I remember also how I felt quite disoriented after the triple-immersion baptism, even though I tried to brace myself for it. I remember particularly how, after my head raised up the final time, the first thing I recognized was a brightly-lit yet very blurry altar table, far away (me being in the Narthex, and it being the Holy Table) but complete with the golden candlestand, fans, tabernacle, etc. The first image imprinted on the eyes of a new-born Christian. I remember, also, feeling unworthily accepted and honored as the priest anointed me with the chrism. I could do nothing but stand there and receive the grace of God as the priest announced each time, "the seal of the gift of the Holy Spirit" the people joyously responding, "Amen!" It was quite surreal. I still have the same surreal feelings sometimes at the Liturgy. Sometimes I do still catch a tear running down my face, and I've cried at every Pascha.
Again, let me frame for you that I had quite out-right rejected the emotionalism of by background by the time I stumbled upon Orthodoxy. Yet, I can be emotional at times at these very Liturgical services. And, you're right, it's not about emotion. It's true whether we happen to feel it or not. I can go to a Liturgy and know God is there and be so keenly aware that I partake of the Body and Blood of my Lord and God and Savior Jesus Christ...other times not so much, I just go, partake, etc. like it's no big deal. It happens, and that's perfectly okay.
Also, I do believe I've been some kind of Christian since I was eight. Was I saved? Well, that's not really the right question. The Orthodox understand that salvation is a process, unlike the baptists who tend to view it as a one-time decision. I am saved, am being saved and (Lord, have mercy) will be saved. That's all I can say. However, I do believe there was a certain Christ-likeness to how I wanted to live my life (no matter how miserably I fail at it to this day). However, becoming Orthodox meant coming into the fullness of what it means to be Christian. It meant being truly Catholic (which is a Greek word simply meaning "according to the whole" meaning, "not lacking in any single thing, complete"). My faith before was incomplete. Now, it is complete. I just have to live in it.
Also, I've heard different stories about how converts feel after their baptism. Some do seem to experience a lightening, a relief. This was the case for me. Others feel no different. Yet others feel persecution tighten...things get worse. All sorts of things happen after baptism. None of them, nor lack of any of them, mean anything.
Sorry this post is so long, but I hope my story and what I've shared is helpful to you. May our Lord Jesus Christ continue to guide you on your journey.
