Now as He walked by the sea of Galilee, He saw Simon and Andrew his brother casting a net into the sea: for they were fishers. And Jesus said unto them, Come ye after Me, and I will make you to become fishers of men. And straightway they forsook their nets, and followed Him. – Mark 1:16-18

It is a great help to a man to find godly work-fellows. If he must needs go a-fishing like Peter, it is a grand thing to have a James and a John as one’s partners in the business. How helpful it is to piety when Christian men associate from day to day with their fellow Christians, and speak often one to another concerning the best things. Firebrands placed closely together will burn all the more freely, coals laid in a heap will glow and blaze, and so hearts touching hearts in divine things cause an inward burning and a sacred fervor seldom reached by those who walk alone. Many Christians are called to struggle hard for spiritual existence through having to work with unbelievers; they are not only sneered at and persecuted, but all sorts of doubts and blasphemies are suggested, and these materially hinder their growth in the heavenly life. When they are brought into this trial in the course of providence they have need of great grace to remain firm under it. Beloved brother, if in your daily business you meet with none to help but many to hinder, you must live all the nearer to God, for you require a double measure of grace; but if in the providence of God you happen to be placed where there are helpful Christian companions, do not readily change that position, even though your income would be doubled thereby. I would sooner work with James and John for twenty shillings a week than with swearers and drunkards for sixty. You who reside with really consistent Christians are much favored, and ought to become eminent Christians. You are like flowers in a conservatory, and you ought to bloom to perfection. You live in a lavender garden, and you ought to smell sweetly. Prove that you appreciate and rightly use your privileged position by endeavoring to bring grace to your house, that it may be altogether the Lord’s. ~ C.H. Spurgeon
