The way many of us live relegates God to an afterthought. After we’ve done everything we want to do, spend money on things we want to buy, and talk to the people with whom we want to speak, then we are ready to communicate with God. We owe God the firstfruits of all our offerings (Nehemiah 10:35-37). This implies we also owe Him a tithe on our time. He should get the best of our time, not the leftovers.
To me, this means beginning each day with God. To not begin the day with God is a recipe for disaster. I see how He rejected Cain’s offering but accepted Abel’s (Genesis 4:3-5). I don’t want to insult God with the time I give to Him. It needs to be my very best, and it needs to be the first I have to offer.
