The food that is placed before you this day, and every day, did not come into being instantly, though it may seem like it.
Think about it. What food is there that does not take time to develop? Not only so, but it must have just the right conditions and be prepared for you.
In all likelihood there is not a single food on earth consumed by mankind that did not take at least a few months to grow, and then be harvested, processed, packaged, and prepared before it is consumed in a matter of moments.
This is why, when about to partake of food, it is good discipline to pause and give thanks, because without considerable time and preparation, that which sustains the body and gives enjoyment from eating, will not come about.
Christians know that all good food, like all good things, come from a caring, loving, merciful Father in heaven, Who graciously feeds even those who are His enemies.
They also know that, when it comes to the forgiveness of sins and everlasting life, it was not a matter of instant gratification, but of careful provision of Christ's own body offered up on the Cross at the proper time.
From this, it is good to observe and to learn patience. Moreover it is good to rejoice, because God the Father of our LORD Jesus Christ does all things well.
