If any man be in Christ Jesus He is a new Creature old self has gone behold new thing has cometh, with the mouth confession is made unto salvation and in heart we believe unto righteousness

We are the redeemed of the Lord, we walk by Faith and not in according to what we see or touch, thus faith cometh by hearing and hearing, keeping on hearing the Word of God.
Hebrews 11:1, vs 6, But without faith it's impossible to please God, for anyone who goes to Him must believe that He Exists and He rewards those who seek Him deligently.

2 corinthians 5:17 now therefore if anyone is in Christ Jesus is a new Creature old self has gone behold new things has cometh.
