The Lord’s Service is discipline. That may surprise you if you think of discipline as punishment. But working out is discipline. Wrestling practice is discipline. Eating well is discipline. These disciplines train us for the fight. This service disciplines the mind and body to conform us to the image of God. The Lord, in His graciousness, runs us through this training towards godliness. Just as working out creates a healthy appetite, so the Lord’s Service ought to create a healthy appetite in us for the things of the Lord.
We become like Jesus and so we desire to do what He does, say what He says, eat what He eats; every word that proceeds from the mouth of God. Having tasted of Christ, we know that He is good and we desire more and more of Him.
So, we can see that the Lord’s Table is another place of discipline. We eat and drink of the Lord Jesus and we grow bigger and stronger in Jesus and we need more and more of Christ to sustain us. We do not need more bread and more wine. A little is enough because in them we see that we really already have all of Christ As we grow in Christ, His grace and power are all that we need to sustain us for growth and for the fight of life.
