6 But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.
Verse 6 is an interpretation of verse 5.
6 But without [apart from] faith it is impossible to please Him,
The word “without” means apart from faith. No one can please God apart from faith. The Greek of “to please” means that no one can please God at all without faith (aorist). No one can please God apart from exercising his or her faith.
for he who comes to God must believe that He is,
The word “must” indicates compulsion. There are two compulsory dimensions to pleasing God: (1) believe “that He is” and (2) believe “that He is a rewarder of those who diligently seek Him.” The word “must” is binding. Faith is necessary for a walk with God.
and that He is [becomes] a rewarder
The Greek word for “rewarder” is found only here in the New Testament. The idea is one who pays wages. The word “is” means becomes. God becomes a rewarder of those who diligently seek Him; that is, He will prove that He will reward people with positive volition.
of those who diligently seek Him.
The seeking here is by one who seeks God by faith.
God exists, and He is generous.
The God who exists is a God of grace (1 Pe 5:10–11). It is the nature of God to give, to reward. In His sovereignty He will graciously provide for those who follow Him. God is faithful in rewarding those who seek Him.
Man and God have corresponding natures. That gives them the capacity for fellowship on a personal level. We can walk with God in fellowship with Him (1 Jn 1:6–7). The finite person must yield to the infinite Person.
Cain murdered Abel, but Enoch never died. God has a different plan for each believer
