C.F.W. Walther was the first president of the Lutheran Church in the United States. The following is from a collection of his sermons from Concordia Publishing House. He talks about how we are placed in and used by the Holy Spirit in the vocation we are in for a reason. Dr Martin Luther made vocation an important part of his issues with the Roman Catholic Church. The Roman Church had been teaching that those who are in “religious” vocations are on a higher level than the rest of the worldly vocations. That somehow priests, nuns, monks, do work that is more important. Luther took issue with that in that we are all placed in our vocation by God for His purposes. Therefore since we are in those vocations at God’s behest, we are serving Him to the best of our abilities in that vocation.
As a good Lutheran pastor, Dr. Walther certainly is in tune with Dr Luther’s views. The following is from a sermon he gave based on Luke 5: 1-11:
“In today’s reading, we encounter Saint Peter working diligently in his earthly calling. He explains to Christ that he has worked patiently through the entire night. Although he has caught nothing [no fish], he does not give up the difficult vocation of fishing to seek something more rewarding. Instead, we find him the next morning washing his nets with his partners and preparing to try again.
Every true Christian will work diligently and untiringly. He will not leave his chosen vocation without real cause, recalling the words of the apostle Paul; ‘So, brothers, in whatever condition each was called, there let him remain with God’ (1 Corinthians 7:24). This is not, however, a distinguishing mark of the Christian since unbelievers can also pursue a vocation with dedication and endurance. In some cases, a non-Christian may even surpass a Christian in his devotion to his work.
How, then, does the true Christian show himself to be such by his earthly work? The first thing we notice from Peter’s example is that, although he was very industrious, he laid his net aside and carefully listened to Jesus as soon as He began to preach. Moreover, he permitted Jesus to use his boat as a pulpit when the people on the shore crowded Him from all sides. Finally, when Jesus called him to be a fisher of men, Peter immediately ‘left everything and followed Him’ (Luke 5:11)'”
In the midst of his earthly work, a true Christian shows that it is not the principal activity of his life. Indeed, he places his heavenly calling above his earthly one. He seeks first the kingdom of God and His righteousness. He does not let his bodily work be a hindrance in caring for his soul. He would rather interrupt his bodily support than be without nourishment for his soul from the precious Word of God.
Today’s text tells us even more about Peter. When he let down his net and caught such a great number of fish that the net tore, he did not in any way attribute the success to himself, his diligence, his wisdom, or his worthiness. Instead, ‘he fell down at Jesus’ knees saying, ‘Depart from me, for I am a sinful man, O Lord!’ (Luke 5:8). He regarded his great success as a blessing of Christ alone that he did not earn. Here we see the second way a person reveals in his earthly work that he is a true Christian. He does not believe he can preserve himself by his work, his diligence, and his wisdom. but only be awaiting his daily bread from God’s faithfulness. He does not lose heart if his worked proves fruitless, but instead places his reliance upon God. If his work is crowned with success, he receives it as a gift of grace from His heavenly Father. He does not bind himself to earthly things, but separates himself from them that he might be drawn to Christ all the more.
There is one more way in which Peter demonstrated in his work that he was a true Christian. When Jesus had stopped speaking, ‘He said to Simon, ‘Put out into the deep and let down your nets for a catch”’ (Luke 5:4). His command was completely contrary to the rules of fishing and Peter’s own experience. The best fishing is not in the depths of the open sea but close to shore; it is also not during the day but at night. How does Peter respond? ‘And Simon answered, ‘Master, we toiled all night and took nothing! But at Your word I will let down the nets'” (Luke 5:5). This is how all true Christians work. They are motivated by God’s command because His Word says, ‘By the sweat of your face you shall eat bread’ (Genesis 3:19). Christians therefore daily say, in the conviction of their heart, ‘But at Your word I will let down the nets.”‘
“And gently grant Thy blessing That we may do Thy will, No more Thy ways transgressing, Our proper task fulfill, With Peter’s full assurance Let down our nets again. Success will crown endurance If faithful we remain. Amen (The Lutheran Hymnal p 544:5)
