This is what you have been doing, Malachi tells them. ‘Ye offer polluted bread upon mine altar; and ye say, Wherein have we polluted thee? In that ye say [in effect], The table of the Lord is contemptible’.
All this is done because the people believe in a God that cannot really see what they do. They treat him as if he can be easily deceived into accepting deficient offerings. How that harms the worshipper! When we diminish God in order to avoid obeying him from the heart, he withdraws from us, and we lose any real communion with him.
That has come back today even in the churches. The rules of the New Testament are very often just completely abandoned, and people create their own methods of evangelism, their own methods of worship, their own methods of singing, their own methods of behaving and dressing – studied informality – and the same ills have repeated themselves. We have churches today, and they are supposed to be Bible believing churches and yet they are doing things which are massively against the Bible, grossly offensive to God. Yet they say, 'Why would you be critical of us? What are we doing?’ They have borrowed worldly music, worldly methods, and you say, 'This is wrong' 'How is it wrong?' they want to know. You can get used to doing things that are wrong; you justify them and you no longer see they are wrong.
