When the Pharisees gathered round Jesus in the temple, they asked Him to tell them plainly who He was. He had already told them plainly who He was, but they didn’t believe Him. So Jesus told them if they did not believe His words, they should believe His works.
If you do not believe what the Bible says, then you should believe its works. So then, faith cometh by hearing and hearing by the word of God. Everyone knows someone who has been born again, someone who has been saved, someone who has received God’s Son, Jesus Christ, as their only hope of salvation and their life was changed. Therefore, if any man be in Christ, he is a new creature, old things are passed away; behold, all things are become new. II Corinthians 5:17
The world is full of testimonials to the life changing grace of God bestowed on those who have received Jesus Christ as their only hope of salvation. Individuals from every nation, every tongue and race, young and old alike on the face of the earth are living examples of a relationship with God through His Son, Jesus Christ. Consider the works of those whose lives give testimony to the truth of the Bible.
A changed life is the work of Christ.
…let the word of Christ dwell (take up its life) in you richly…
