Come unto me, I am the way the truth and the life, no one comes to the Father except through me John 14:6

Matthew 11:28-30
Come unto me, all ye that labour and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For my yoke is easy, and my burden is light.

Questions:

1. If Jesus is the way the truth and the life, why do a Christian who follow Christ with everything he had, live in pain and die like a pagan?
2. If Jesus is the way to the Father, why can’t we see the way physical to work through it?
3. Who has come to Christ and find rest for his soul?
