But those who wait on the Lord Shall renew their strength; They shall mount up with wings like eagles, They shall run and not be weary, They shall walk and not faint. Isaiah 40:31

Be of good courage, And He shall strengthen your heart, All you who hope in the Lord. Psalm 31:24

For God has not given us a spirit of fear, but of power and of love and of a sound mind. 2 Timothy 1:7
