Jesus spoke in John chapter 6:
63 It is the Spirit who gives life; the flesh profits nothing. The words that I speak to you are spirit, and they are life.
The Words of Jesus and His manifested acts are the basis of our salvation and our life. Any issues we may confront throughout our life can ultimately be resolved by hearing The Word.
