Hebrews 11:6 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.

Faith is an important part of Christianity.
It’s one thing to know because you’ve saw something.
It’s another to believe despite not seeing something.
Jesus told Thomas, “Thomas, because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed.” John 20:29
That’s you and me!
Today’s verse says you cannot please God without faith.
Paul said in Rom 14:23 – whatever is not from faith is sin.
What does this say about those that met or talked with God like Abraham, Moses, David, Solomon, or anyone that walked with Jesus?
Each of them still had to live by faith to believe those things God said would come true.
You and I live the same way, by faith in what God said in His word.
