and sent Timothy, our brother and God's servant in the Gospel of Christ, to establish you, and to comfort you concerning your faith;
      (2.) The consequence the apostle feared was lest his labour should be in vain. And thus it would have been, if the tempter had tempted them, and prevailed against them, to move them from the faith. They would have lost what they had wrought, and the apostle would have lost what he laboured for. Note, It is the devil's design to hinder the good fruit and effect of the preaching of the gospel. If he cannot hinder ministers from labouring in the word and doctrine, he will, if he be able, hinder them of the success of their labours. Note also, Faithful ministers are much concerned about the success of their labours. No one would willingly labour in vain; and ministers are loth to spend their strength, and pains, and time, for nought.
