He that saith, I know Him, and keepeth not His commandments, is a liar, and the truth is not in him.@1 John 2:4

Christian G. Neefe (1748-1798)

Who keepeth not God’s Word, yet saith,
I know the Lord, is wrong;
In him is not that blessèd faith
Through which the truth is strong;
But he who hears and keeps the Word,
Is not of this world, but of God.

The faith His Word hath caused to shine
Will kindle love in thee;
More wouldst thou know of things divine,
Deeper thy love must be;
True faith not only gives thee light,
But strength to love and do the right.

Jesus hath washed away our sin,
And we are children now;
Who feels such hope as this within,
To evil cannot bow;
Rather with Christ all scorn endure,
So we be like our maker pure!

For he doth please the Father well
Who simply can obey;
In him the love of God doth dwell
Who steadfast keeps His way;
A daily active life of love,
Such fruits a living faith must prove.

He is in God, and God in him,
Who still abides in love;
’Tis love that makes the cherubim
Obey and praise above;
For God is love, the loveless heart
Hath in His life and joy no part.
