GSW: The Measure of faith! The article must not be left out. It is key. A thing. It means the writer is referring to a Noun. An object or a subject. Every believer received this thing when they became born again. What did we receive pls? That is what he is referring to. With it we all know we have faith. Without it we cannot say Jesus is Lord. What did we receive at salvation. Any takers?

Considering, Jesus Christ:
If I see JESUS in you 10% and you see Jesus in me 50% How much of him you reveal is how much you have grown in faith. It means I have used my measure of faith more effectively than you. I will also have more result. There is no need for me to be proud or be boastful. Christ will be revealed all by Himself in us for the world to see.
