‘Believing’ the facts, begins with acceptance of the claims of Jesus that He is the Lord from heaven and He is now risen from the dead.
‘Faith’ in the person, is acknowledging His trustworthiness and ability to save.
‘Trust’, is the yielding of the heart and soul, so as to depend on Him for everything for all eternity.
‘Follow’ is the commitment to Him, His word, His leading, His future.
Note in Bible usage, all of these are frequently implied in the use of just one of them.
“Believe on the Lord Jesus Christ and you will be saved” Acts 16.31
