The way of Jesus is the only way to be right with God.

John 6:25-68
When following Jesus you will face moments when your confidence in Him will be tested.
Remember the words of Peter:
Simon Peter answered him, “Lord, to whom shall we go? You have the words of eternal life. We have come to believe and to know that you are the Holy One of God.”  John 6:69-69 (NIV)
Remember the words of Hebrews 9:15:
For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance—now that he has died as a ransom to set them free from the sins committed under the first covenant.  Hebrews 9:15 (NIV)
The way of Jesus is the only way to be right with God.
