God hath work to do in this world; and to desert it because of its difficulties and entanglements, is to cast off His authority. It is not enough that we be just, that we be righteous, and walk with God in holiness; but we must also serve our generation, as David did before he fell asleep. God hath a work to do; and not to help Him is to oppose Him.
John OwenI have known some good men who have been so addicted to their study, that they have thought the last day of the week sufficient to prepare for their ministry, though they employ all the rest of the week in other studies. But your business is to trade with your spiritual abilities. ... A man may preach a very good sermon, who is otherwise himself; but he will never make a good minister of Jesus Christ, whose mind and heart are not always in the work. Spiritual gifts will require continual ruminating on the things of the Gospel in our minds.
John OwenTemptations and occasions put nothing into a man, but only draw out what was in him before.
John OwenWhen we realize a constant enemy of the soul abides within us, what diligence and watchfulness we should have! How woeful is the sloth and negligence then of so many who live blind and asleep to this reality of sin. There is an exceeding efficacy nad power in the indwelling sin of believers, for it constantly inclines itself towards evil. We need to be awake, then, if our hearts would know the ways of God. Our enemy is not only upon us, as it was with Samson, but it is also in us.
