Jesus Christ is the same yesterday, today, and forever. – Hebrews 13:8

I would like to put this personally to any tried child of God here. Are you going to let go your God because you have lost His smile? Then I ask you, Did you base your faith upon His smile? If you did, you mistook the true ground of faith. The ground of a believer’s confidence is not God’s smile, but God’s promise. It is not the temporary sunshine of His love, but His deep eternal love itself, as it reveals itself in the covenant and in the promises…Oh! Come then to this. The promise is as good as ever. Christ is the same as ever; His blood is as great a plea as ever; and the oath of God is as immutable as ever. We must get away from all building upon our apprehensions of God’s love. It is the love itself we must build on-not on our enjoyment of His presence, but on His faithfulness and on His truth. Therefore, be not cast down, but still call Him, “My God.”

Moreover, I may put it to you, if, because God frowns, you give Him up, what else do you mean to do? Why, is not it better to trust in an angry God than not to trust in God at all? Suppose thou leavest off the walk of faith, what wilt thou do? The carnal man never knew what faith was, and, therefore, gets on pretty fairly in his own blind, dead way; but you have been quickened and made alive, enlightened, and if you give up your faith, what is to become of you? Oh! hold to Him then.

“For if thine eye of faith be dim,
Still hold on Jesus, sink or swim;
Still at His footstool bow the knee
And Israel’s God thy strength shall be.”

Don’t give Him up. ~ C.H. Spurgeon
