Titus 3:1

Here is the fourth thing in the matter of the epistle. The apostle had directed Titus in reference to the particular and special duties of several sorts of persons; now he bids him exhort to what concerned them more in common, namely, to quietness and submission to rulers, and readiness to do good, and to equitable and gentle behaviour towards all men - things comely and ornamental of religion; he must therefore put them in mind of such things. Ministers are people's remembrancers of their duty. As they are remembrancers for the people to God in prayers (Isa 62:6), so are they from God to them in preaching: I will not be negligent to put you always in remembrance, Pe2 1:12. Forgetfulness of duty is a common frailty; there is need therefore of reminding and quickening them thereto. Here are the duties themselves, and the reasons of them. I. The duties themselves, which they were to be reminded of. 1. Put them in mind to be subject to principalities and powers, to obey magistrates. Magistracy is God's ordinance for the good of all, and therefore must be regarded and submitted to by all; not for wrath and by force only, but willingly and for conscience' sake.
