Lastly, take the other suggestion, that every day has its own supplies.
That does not lie in the text properly, but for the sake of completeness I add it. Every day has its own supplies. The manna fell every day, and was gathered and consumed on the day on which it fell. God gives us strength measured accurately by the needs of the day. You will get as much as you require, and if ever you do not get as much as you require, which is very often the case with Christian people, that is not because God did not send enough manna, but because their _omer_ was not ready to catch it as it fell. The day's supply is measured by the day's need. Suppose an Israelite had sat in his tent and said, 'I am not going out to gather,' would he have had any in his empty vessel? Certainly not. The manna lay all around the tent, but each man had to go out and gather it. God makes no mistakes in His weights and measures. He gives us each sufficient strength to do His will and to walk in His ways; and if we do not do His will or walk in His ways, or if we find our burden too heavy, our sorrows too sharp, our loneliness too dreary, our difficulties too great, it is not because 'the Lord's hand is shortened that it cannot' supply, but because our hands are so slack that they will not take the sufficiency which He gives. In the midst of abundance we are starving. We let the water run idly through the open sluice instead of driving the wheels of life.
My friend! God's measure of supply is correct. If we were more faithful and humble, and if we understood better and felt more how deep is our need and how little is our strength, we should more continually be able to rejoice that He has given, and we have received, 'even as the duty of every day required.'
