I realize this is a big question, but can you elaborate?
I'd also like to hear how you would answer the same question, Thunderian, since you sound very sure. I wish to move closer to God. My faith is more of an intuition and I do not feel grounded strongly enough to be able to refute any other faith on a purely theological/intellectual basis. Being a skeptic at heart I wish to shred any doubt I'm not simply falling victim to my own subconscious psychology.
That 'intuition' is *very* strong right now though... Jesus Christ is just all that makes sense.
Don't worry about refuting any other faith for now. Jesus Christ is wooing you, and it's wonderful.
My own journey to where I am now in Jesus Christ is a long one. I was raised in a Christian home, and got saved when I was very young, so I really don't know what it's like to be without Christ. That is not to say that I always honoured him or lived a life that was pleasing to him, because I most emphatically did not. I never got grounded in my faith when I was younger -- I didn't pray regularly, read my Bible or have any good habits like that -- and when I left home I wandered far from God.
It wasn't until I had exhausted what the world had to offer and was at about the lowest ebb I could have ever imagined that I finally opened my Bible again and remembered that God loves me. It was a long process from that day to the confidence I have in Jesus Christ today. I had always had my parent's faith, but even though I was saved, I had no personal beliefs or knowledge, and after 25 years of being a Christian, I had to learn what it meant.
Two things stood in my way that I can see. The first was my own sense of worthlessness. How could God love me when I had not only accepted and then spurned his love, but had gone on to explore every depraved imagining of my heart? So I learned about Jesus Christ's righteousness, and how when we accept him we are covered by it. When we accept that we are sinners, and confess our sins to Jesus Christ, he has promised to forgive us. If God forgives me, who am I to hold a grudge against myself? If I believed that Jesus loved me, I couldn't hate myself any longer. I know now that self-hatred and feelings of worthlessness are from Satan. The answer to is to know your Bible -- know the promises of God to believers -- and know how much God loves you.
The second thing that I had to get over was my faith in the Bible itself.
Nothing is attacked so frequently, so vehemently and with such hatred as the word of God. And the sad fact is that even most Christians today don't fully trust the Bible. It can be a hard book, with hard words, and we are inundated with people telling us that it's wrong, it's silly, it's hateful and outdated. The first thing that Satan is recorded in scripture as saying is, "Yea, hath God said ...?", essentially asking,
did God really say that? And that is at the heart of every false religion, every attack on God's word, and every New Age spin on scripture.
I doubted the Bible. I doubted that God had really condemned homosexuality, because I had gay friends and I loved them and didn't see why God wouldn't want them to be happy. I doubted that sex outside of marriage was wrong, because I was lonely, and God didn't want me to be lonely, did he? I doubted all kinds of things that were plain in scripture, but weren't in line with what I felt in my heart, or didn't seem to line up with what science or history was telling me. This was at the same time as I was struggling with the feeling that God didn't really love me, so if I doubted the parts of the Bible I didn't want to believe, or were difficult, then you can see how it wasn't too hard to doubt the parts of the Bible that I didn't feel like I could believe. Once you start doubting, where do you stop? So all Satan has to do is make you doubt one thing in scripture, and you will start doubting other things for yourself.
Of course, I didn't see it that way. I just knew that some parts of the Bible were unbelievable, and that I was having a hard time believing that God loved me. I didn't see that they were connected. One day, however, I read this verse in Proverbs:
There is a way that seemeth right unto a man, but the end thereof are the ways of death.
That hit me pretty hard. The ideas I had and the ways that I lived that were contrary to the Bible
seemed right to me. But these ways were not God's ways. I had to make a decision then to either believe the whole Bible -- every jot and tittle, as Jesus said -- or continue in my unfulfilling Christian walk. I chose to embrace the word of God, and let him show me how it was true. I asked God to help my unbelief, and he has been faithful to show me the answer to every question I have had of him regarding scripture. I found some good teachers (including Chuck Missler, may God bless him) who loved and trusted God's word completely. Some of the answers I sought took years for me to learn to my satisfaction, but I have learned to approach apparent problems in the Bible with the faith that the answer is there -- I just need to seek it out with God's help. I have 100 percent confidence that the Bible is the word of God, preserved for us as he promised, and that it's his message to the world that he died and rose again for.
Sorry if this sounds like proselytization. I don't know any other way of answering the question I was asked.
I'll pray for you, SkepticCat, that God will lead you into a secure understanding of his word, and of his love for you.
