Malachi Reminds me of James 4:8 where God says to draw near to Him and He will draw near to you. In this case the people and the priests are, in effect, saying to God, you haven’t drawn near to us so what’s the point of drawing near to you. They are half-heartedly going through the motions when doing those things God expects and even challenging him when he points out their shortcomings. Without seeking God and drawing near to him they lack the motivation to give God their best. They rob God by withholding their tithes and even divorce their wives in order to marry foreign women and worship their idols.
