John 14:6 Jesus told him, "I am the way, the truth, and the life. No one can come to the Father except through me.
That sentence only says that nobody gets to god without going through Jesus first, it does not say that any specific belief is asked or required. Just like I get to the airplane through the terminal. I don't have to believe anything about the terminal.
The specific belief is written right there - belief in Him - Jesus or the Christ, Messiah, anointed One of God. Believers weren't called Christians at first, and all who call themselves by His name today aren't always telling the truth. Belief is a trust that He will do what He says He will do and that He is who He says that He is.
Faith in Jesus Christ as God is repeated continually throughout scripture, and it is said that all knees will bow to Him someday as King of Kings. He alone is worthy of that title, having suffered and died for mankind. Why you say you cannot see that the scriptures do not speak of a specific belief, I can't quite figure, but I believe you will find the answer if you keep seeking with all your heart and refuse to narrow your mind to all that is possible with God. Here is just a few more of many scriptures speaking of who Jesus is. He is the living word of God that walked among men, by whom all things were created. He was God's presense with man until He left to prepare a place for us and intercede for us before the Father, sending His Holy Spirit as a comforter and helper until His return. All these manifestations of God have one purpose, and that is to benefit the object of His love, the Church, but don't be put off by the word "Church", as in the Greek ecclesia just means a group or gathering of people who believe and trust in Him - not by just words, but with their actions. It is easy to say we believe in something, but the rubber hits the road by how we act upon the word of God - whether it is truly alive in us or just a mental assention. God gives us grace to grow towards a strong faith. He gives us this time to seek Him and know Him by faith. Life is a gift given to us to wonder at and then seek the Author of it. When I first started out, I didn't have clue, but I was determined to know once I knew that there was no way I could put off the truth that this life had to come from a Master of such incredible design that I could barely find words to cover the beauty and complexity of it. I have found that as the truth is found there is less gray area, as long as we keep walking towards the light. His truth that is light dispells the gray from our lives the closer we get to Him, but the Bible says that some men prefer the darkness so that their own deeds are not brought into the light. I can testify this to be true in my life, and I only offer encouragement to you to keep considering the words Jesus spoke to us and the words He continued to speak to us through the Holy Spirit that inspired His servants like the apostle Paul. Continue, and I know you will find life and answers to all questions, Just don't close the doors to the literal meaning of Jesus words about who He said He was and is. This is my hope and prayer for you.
