The year is going by fast with August starting this week.  School will be starting and students will return to classes to do their best.  The idea from Sunday that we need to do our best is not a new one.  God not only deserves our best but he also expects it.  By giving our all in everything we say and do, we show God how much he means to us and in turn God promises to bless us when we do.  Again, the passage from Malachi about testing God is the only time God makes this declaration.  If we are faithful in giving to God what he asks, he will throw open the heavens and we will be blessed.  I would add giving cheerfully and with a heart for God but that is what we are promised.  I hope you are going to test God this week by giving him your best.
