We judge things by their present appearances, but the Lord sees them in their consequences. - John Newton

[ ... ]when we have been brought very low and helped, sorely wounded and healed, cast down and raised again, have given up all hope — and been suddenly snatched from danger, and placed in safety; and when these things have been repeated to us and in us a thousand times over, we begin to learn to trust simply to the word and power of God, beyond and against appearances[....]

We have no Scriptural evidence that we serve the Lord at all, any farther than we find a habitual desire and aim to serve him wholly.
He is gracious to our imperfections and
weakness; yet he requires all the heart, and
will not be served by halves, nor accept what is performed by a divided heart.

The earth shall soon dissolve like snow, The sun forbear to shine; But God, who call'd me here below, Will be forever mine.
