He has promised deliverance from fear.
Through forgiveness, Christ provides complete deliverance from the penalty of sin.
"You were dead in sins, and your sinful desires were not yet cut away. Then He gave you a share in the very life of Christ, for He forgave all your sins, and blotted out the charges proved against you, the list of His commandments, which you had not obeyed. He took this list of sins and destroyed it by nailing it to Christ's cross." Colossians 2:13-14, TLB
"And it shall come to pass, that whosoever calls on the name of the Lord shall be delivered, for in Mount Zion and in Jerusalem shall be deliverance, as the Lord has said, and in the remnant whom the Lord shall call." Joel 2:325
