I'm sorry, it's late and so I didn't read everything in this thread, but I do have some things on my heart to share with you:
1. It is NOT us who makes ourselves believe but it is instead God who calls us, unhardens our heart, w/e, to Himself and reveals to us His salvation plan through Christ. So when you say "I am unable to believe....I just can't believe" what have you, you are speaking the truth. It is only by God's love and His grace that He makes it possible for those whom believe, to believe.
Ephesians 2:8-10
8For it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God— 9not by works, so that no one can boast. 10For we are God's workmanship, created in Christ Jesus to do good works, which God prepared in advance for us to do.
Verse 8 & 9 clearly state, it is not by from us that we have the gift of salvation. There is nothing, and I mean nothing, WE can do for ourselves to be saved. Instead it is God's work in us that saved us. It is Him who called us before we called unto Him. Therefore just as verse 9 says it is "not by works".
2. As for God "sending people to hell". (inc. those who have never heard His name). First off, we don't know who God does and who God doesn't send to Hell. Second, He's God, it doesn't matter whom He does or doesn't. He created us, He is God, if we don't accept Him, we get what we deserve. He chooses to whom He reveals Himself and to whom He doesn't. Through Scripture says that Creation itse;f testifies to God's workmanship. Still yet though He is God, He is the one that made us to do what He wills with. So if He made some for hell and some for Heaven, who are we to say it is right or wrong of Him? And more importantly, what other choice do we have but serve Him? If we don't we will probably (Scripture says) spend eternity in Hell (absence from Him). So am I not going to serve Him, because He does things I don't like with His own Creation? I don't think so lol.
So for me, when all is said and done. I praise God He called me out of the muck and mire of the world and into a wonderful loving relationship with the God whom created all things! For me, eternity has already started and it is good! Guess what. For you it has started as well...you're already living in absence of God in your life...in other words...Hell.
I will def pray for you that God reveals Himself to you and that you'll be of mind and heart to realize it.
God bless!
