When did the Israelites gather manna? Exodus 16:21 shows that they had to gather their daily bread first thing in the morning, before the sun got hot, or their opportunity literally melted away. God's bread is best gathered early in the day, when we first arise, when we and the manna are at its freshest. This sounds like "seek first the kingdom of God. . . "! Sometimes, we intend to study later in the day, or in the evening, and what happens? Other things interfere and crowd out the Word of God—and an opportunity to show God He has first place in our life simply melts away, just like manna allowed to sit in the heat of the sun.
In this regard, fathers and mothers should teach their children by example to help them learn this habit. Teach them that the best time to study and pray is right after waking up. Ask them to make their beds and immediately kneel to talk to and worship their Father in heaven.
None of this works unless we get up in time to put God first, and that will not happen unless we go to bed early enough! To show God we are serious about putting Him first in our lives, perhaps we need to quit doing the things that eat up our time. God will not just slide into first place. We must consciously put Him there. We must make this decision every day of our lives. God will not accept second or third place in our lives.
