Your faith is lamentably weak. Yes, but look up to Jesus seated at the right hand of power in the heavens. It is not a question of you and your abilities, but of Him. Left to yourself, the world and the powers of evil will easily overcome you, but with Christ in command, you may safely sing—
"When I fear my faith will fail, Christ can hold me fast."
Will you not trust Him for this, and boldly confess His name?
