Robert- I appreciate the way you phrased that: "...in the process of becoming a Christian". It really is a process. The Bible tells us in
John 1 that "As many as received Him, to them He gave power to BECOME the sons of God". The "becoming" starts when we accept Jesus and continues throughout life, in my opinion.
That being said, and in relation to the term "sons of God", I'll point you to another verse.
Rom 8:14
For as many as are led by the Spirit of God, they are the sons of God.
Our quest to becoming sons (and daughters) of God begins when we repent of our sins and continues as we are led by His Spirit. As you venture into the tangled world of beliefs, you'll find an incredible and confusing maze of differing views and opinions. It will be difficult if not impossible to "decide for yourself what to believe" by listening to all the voices you'll hear. There is ONE VOICE you should give heed to. And that is the voice of the Lord, speaking to you from His Word. The Bible says His sheep will only hear and follow the voice of the Shepherd. The fact is everyone thinks their belief is right. I believe (and hope) I'm right. And, I think I am, because I try to "examine myself (and My beliefs ) often to ensure they are right with the Bible.
2Co 13:5 Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates? As I said, I believe and hope I'm right. But one thing is for sure. The Word of God is right, and as long as I stay true to it, I'm right.
I encourage you to continue in your studies. Prayerfully study His Word and allow the Holy Spirit to lead you.
Jhn 16:13
Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
