Believe on the Lord Jesus Christ, and thou shalt be saved. (Acts 16:31.)
But what does it mean to believe?
One must have faith in Him.
But what is faith?
Faith—saving faith—consists of your believing that Jesus Christ came to save the lost—acknowledging yourself as a lost creature—accepting Him as your own personal Saviour. In your helplessness, your dependence is entirely on the faithfulness of God and a firm trust that He will fulfill all His promises.
For he that cometh to God must believe that He is, and that He is a rewarder of them that diligently seek Him. (Hebrews 11:6.)
It is not trusting to services, rituals or sacraments. Saving faith believes the gospel record, accepts the gospel offer and trusts God for its complete fulfillment.
But—he that believeth not God hath made Him a liar; because he believeth not the record that God gave of His Son. (1 John 5:10.)
“Saving faith”—or “making God a liar.” Which do you choose?
