John 5:38 And ye have not his word abiding in you: for whom he hath sent, him ye believe not.
This is a wild statement. If you do not believe Jesus then the Word doesn’t abide in you. I see so many important truths in that.
Jesus is the Word. If you say you believe in Jesus then you have to believe in the Word.
You say you can’t understand the Word but you refuse to believe in Jesus then you make it clear what the problem is. The Bible is about Jesus. It is Jesus. So Jesus is the key to understanding the Bible.
If you want the Word of God to mean something and to work in your life then believe in Jesus!
