Belief, Trust, Consent, Agree.  All four words are commonly confused.

Example:

Do you agree the chair is safe?  (no action performed)

Do you consent to sit in the chair? (still no action)

Do you trust the chair? (first action)

Do you believe in the chair? (continuing action)

Belief is commonly used for agree or consent, but belief requires action.  When you truly believe, you can transmit your belief as faith to another person.

When you trust, you do something.  When you believe, you continue to do something.

“Believe in the Lord Jesus Christ and be saved.”

“If you believe in me, you will keep (do) my commandments”

Understanding that belief is beyond agreement, beyond consent and beyond trust.  It is foundational to faith.

“Show me your faith without your works, and I will show you my faith BY my works.  Faith without works is dead.”
