“Don’t be impatient. Wait for the Lord, and He will come and save you! Be brave, stouthearted and courageous. Yes, wait and He will help you” Psalm 27:14
His father in the faith, the apostle Paul, reminded him, as recorded in 2 Timothy 1:7, “For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind“. That is the reason our Lord promised, in Acts 1:8, “Ye shall receive power, after that the Holy Ghost has come upon you: and ye shall be witnesses“.
The Holy Spirit is the only one who can enable us to overcome fear. So, as we claim the promises of God and appropriate the fullness and power of His Holy Spirit, we can know that courage.
