Malachi 1:13
Ye said also, Behold, what a weariness is it! and ye have snuffed at it, saith the LORD of hosts; and ye brought that which was torn, and the lame, and the sick; thus ye brought an offering: should I accept this of your hand? saith the LORD.
The verse exposes Israel and its priests as dishonoring God by calling His service a weariness and snuffing at it with contempt, treating worship as a burden to be performed grudgingly and carelessly. Their contempt appeared in bringing as offerings animals that were torn and lame and sick and otherwise damaged and unfit, while keeping the good for themselves, in direct violation of the requirement to bring only perfect animals without blemish. God rejects such offerings as unacceptable, asking whether He should accept this of their hand. What is offered to God must be fitting and acceptable, the best and without blemish, given freely and generously and not as sparingly and as little as possible. A vow to God is not honored by presenting a corrupt thing, but must be faithfully paid as promised, and withholding what was vowed profanes what is sacred.
Withholding a proper share brought judgment in poor harvests and flocks and affliction in families, while giving freely was connected with blessing on families and possessions. The same principle applies to the body, which is to be presented as a living and holy and acceptable sacrifice rather than one corrupted by damaging habits, through daily practices that preserve physical and mental and moral health. The same principle applies to building a place of worship, where God's people should give generously of their means and share in providing what is suitable and comfortable, rather than treating what they spend for worship as wasted or as a loss. Small, stinted gifts from professed believers contradict their claim to believe that Jesus is coming, for Jesus knows their works and hates such offerings.
A church purpose does not make corrupt means of raising money acceptable, so funds obtained through lotteries and games and fairs and dances and festivals and luxurious feasts are defective, lame and diseased offerings that can lead young people toward ruin. Letting guests and entertainment leave people too weary to pray presents God with a lame offering, so prayer should be given an unhurried and attentive and grateful place.
