But let them ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed. James 1:6.

Looking unto Jesus, not only as our Example, but as the Author and Finisher of our faith, let us go forward, having confidence that He will supply us with all the strength that is needed for every duty.
