I recognize the Bible states that God "predestines" us (Christians) for a future with Christ in Heaven [Ephesians 1:4-6, Romans 8:29-30, Romans 11: 5-6] and that he does NOT predestine others to Hell (1 Timothy 2:4, 2 Peter 3:9]; however, does this mean that only a few of the Christians on Earth were predestined by God and the rest "happened" to come to Christ by the work of these Christians and the Holy Spirit? Or were ALL the people who God knew would become Christian through His omniscience thus "predestined" by Christ?
When the Great Tribulation comes, how can people be saved? Is it still by faith or plain works?
 Are tongues for today?  Are they unknown or known tongues and what is the meaning of angelic tongues?  Can you explain 1 Corinthians 14 to me; this is the chapter that my relatives say proves that speaking in tongues is for today.
Will God, through the Holy Spirit, finally give up on calling someone for salvation, if the person continues to reject the call?
Can you please explain 1 John 5:16. This verse confuses me. I have heard several explanations, but they don't quite make sense. examples-do not pray for those unreceptive to the Gospel, but the wording of the last sentence implies that you don't have to, not don't. What do you think about it?
I am trying to find scriptures on where God came from. Can you please direct me?
