When I was a child, I believed in God, but I had no idea just how faithful He is. I think one of the reasons it is so important for those that follow Christ to truly follow His teaching is because we are the only living source in the flesh on the face of the earth that could possibly point someone in the right direction.
Now you may ask yourself, "What is the 'right' direction?". The right direction is pointing them to God.
I recently had a conversation with someone that informed me that they talked to God and had no need for Christ Jesus in the mix. There was a point in my life when I had no idea who Christ truly was and I might have uttered something as foolish myself back in those days.
One thing that cannot be argued is that Scripture speaks truth. Often people will take a verse and use it out of context which is why it is so important for you to understand God's word for yourself. As you study His word you'll realize you have to read it in context. You have to know what was going on in the world at the time of the writing and so much more. Another great thing to remember is Scripture does not contradict itself so, if something is mentioned in one book, you should be able to find a verse in another book that speaks to this same truth. With that being said, Scripture tells us that Jesus Christ is the only way to eternal life.
Jesus said to him, "I am the way, and the truth, and the life; no one comes to the Father but through Me. (John 14:6, NASB)
