Finally, be strong in the Lord and in his mighty power. Put on the full armor of God, so that you can take your stand against the devil’s schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the gospel of peace. In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. Take the helmet of salvation and the sword of the Spirit, which is the word of God.

-- Ephesians 6:10-17

Come, Thou Fount of Every Blessing

Come, thou Fount of every blessing; tune my heart to sing thy grace;
Streams of mercy, never ceasing, call for songs of loudest praise.
Teach me some melodious sonnet, sung by flaming tongues above;
Praise the mount! I’m fixed upon it, mount of God’s unchanging love!

Here I raise my Ebenezer hither by thy help I’m come;
And I hope, by thy good pleasure, safely to arrive at home.
Jesus sought me when a stranger, wandering from the fold of God;
He, to rescue me from danger, interposed his precious blood.

O to grace how great a debtor daily I’m constrained to be!
Let that grace now, like a fetter, bind my wandering heart to thee.
Prone to wander, Lord, I feel it, prone to leave the God I love;
Here’s my heart’ O take and seal it; seal it for thy courts above.
