How can the brethren testify

Verse 1
How can the brethren testify
That the true faith resides in me?
On Christ if I indeed rely,
The fruits of grace will shew the tree,
And all my life and actions prove
The principle of humble love.

Verse 2
If still I in the truth abide,
If Christ is manifest within,
I walk like him, nor turn aside,
’Till by the truth from inbred sin
Redeem’d, I feel his utmost word,
One flesh, one spirit with my Lord.
