With so much going on, it would be easy to consider God's part to be part-time. As important as He is, and as busy as you are, it would be more advantageous to your schedule to relegate Him to Sunday. To say a prayer on Sunday. To worship God on Sunday. To read the Bible on Sunday.
Scripture never teaches that.
I'm a Christian on Sunday and live the rest of the time the way I want to. Don't just say a prayer on Sunday. Give all day, every day to God. It's the least we can do for the One who gave those days to us. A fulltime God deserves fulltime followers.
