The Lord Jesus commended the widow's two mites because it was all she had, yet in that where He actually requires one day of seven for his folk to devote to His worship, we think an hour or two sufficient and then we'll be off to our own matters, pleasures, and entertainments (Isa. 58:13). The widow went "all in" (a questionable analogy I admit) financially in her giving unto the Lord, and we know that pleased Him; yet why are we so stingy we refuse to give Him the Lord's day He commands to be given rather than what our actions say we think He deserves instead, the "Lord's hour"? God hates a half way devotion. Samuel Rutherford preached,
[The Lord] hates a mixture. It is a mark put on Samaria (2 Kings 17:33), [that] They feared the Lord, and served their own gods. This is that which brings the stretched out arm of the Lord’s fury on the land (Zeph. 1:5), because they swear by the Lord, and by Malcom, and because the people halt between the Lord and Baal (1 King 18:21). And it is Jehu’s reproachful reformation (2 Kings10:28, 29). Thus Jehu destroyed Baal out of Israel. Nevertheless he departed not from the sins of Jeroboam the son of Nebat. Oh how fearful to be under this? He is for the good cause, nevertheless, he knows nothing of the power of religion, so he is right in the house, nevertheless he complains much with malignants. It is known to you all when the whore of Babylon was cast out of the church, that she left behind her a gold ring, and some lover tokens, I mean Episcopacy, and human ceremonies. This was the whore’s policy to leave a token behind her that she might find an errand in the house again. And she was indeed returning to the house to demand her love token again, but it shall be heavenly wisdom to make a perfect reformation; keep nothing that belongs to Babylon,and let not a stone to be a cornerstone or a foundation be taken out of Babylon for building of the Lord’s house, for they are cursed stones [cf. Jer. 50].
