A charge to keep I have

Verse 1
A charge to keep I have, (Lev. 8:35, I Tim. 6:20, II Tim. 1:14)
A God to glorify, (I Cor. 6:20, I Cor. 10:31)
A never-dying soul to save, (James 5:20)
And fit it for the sky;
To serve the present age,
My calling to fulfil: (Eph. 4:1)
O may it all my powers engage
To do my Master’s will! (Matt. 7:21, Matt. 12:50)

Verse 2
Arm me with jealous care, (II Cor. 11:2)
As in thy sight to live, (II Cor. 2:17, I Pet. 3:12)
And O! Thy servant, Lord, prepare
A strict account to give: (Matt. 12:36, Rom. 14:12, Heb. 4:13, I Pet. 4:5)
Help me to watch and pray, (Matt. 26:31, Mark 13:33, Mark 14:38, Luke 21:36, Eph. 6:18, Col. 4:2, I Pet. 4:7)
And on thyself rely, (Ps. 37:5, Prov. 3:5)
Assur’d, if I my trust betray,
I shall for ever die. (Ezek. 18:26)
