Hebrews 11:6 But without faith it is impossible to please and be satisfactory to Him. For whoever would come near to God must [necessarily] believe that God exists and that He is the rewarder of those who earnestly and diligently seek Him [out]
Why does God say that it is impossible to please Him without faith? Because faith is trust in Him and if we don’t have faith in Him we are really saying we don’t believe Him or trust Him.
So what’s the answer? He said in this same sentence that He rewards those who earnestly (seriously), diligently seek Him out. I would say that seeking Him would be the same as taking the time to know Him. How do we trust someone we don’t know, how can you trust or have faith in a God whom you are not sure what He is thinking?
If you know God, you can know what He is thinking (1 Corinthians 2:16). If you know God you know the things that are to come (John 16:13). If you know God He will share His mysteries with you (Mark 4:11), thus if you know God and you know what He is doing, you will also have peace and that peace is your rest (Hebrews 4:11), your faith in knowing Him.
