How long halt ye between two opinions? if the LORD be God, follow Him: but if Baal, then follow him. -1 Kings 18:21

What a splendid general confession is that in the Church of England Prayer Book: “We have erred and strayed from Thy ways like lost sheep; we have done those things which we ought not to have done, and we have left undone those things which we ought to have done, and there is no health in us.” There is not to be found a finer confession in the English language… I like an out-and-out man of any sort. Give me a man that is a sinner: I have some hope for him when I see him sincere in his vices, and open to acknowledging his own character; but if you give me a man who is half-hearted, who is not quite bold enough to be all for the devil, nor quite sincere enough to be all for Christ, I tell you, I despair of such a man as that. The man who wants to link the two together is in an extremely hopeless case. Do you think, sinners, you will be able to serve two masters, when Christ has said you cannot? Do you fancy you can walk with God and walk with mammon too? Will you take God on one arm, and the devil on the other? Do you suppose you can be allowed to drink the cup of the Lord, and the cup of Satan at the same time? I tell you, ye shall depart, as cursed and miserable hypocrites, if so you come to God. God will have the whole of you come, or else you shall not come at all. The whole man must seek after the Lord; the whole soul must be poured out before Him; otherwise it is no acceptable coming to God at all. Oh, halters between two opinions, remember this and tremble. ~ C.H. Spurgeon
