3:1-5 Those who are far apart still may meet together at the throne of grace; and those not able to do or receive any other kindness, may in this way do and receive real and very great kindness. Enemies to the preaching of the gospel, and persecutors of its faithful preachers, are unreasonable and wicked men. Many do not believe the gospel; and no wonder if such are restless and show malice in their endeavours to oppose it. The evil of sin is the greatest evil, but there are other evils we need to be preserved from, and we have encouragement to depend upon the grace of God. When once the promise is made, the performance is sure and certain. The apostle had confidence in them, but that was founded upon his confidence in God; for there is otherwise no confidence in man. He prays for them for spiritual blessings. It is our sin and our misery, that we place our affections upon wrong objects. There is not true love of God, without faith in Jesus Christ. If, by the special grace of God, we have that faith which multitudes have not, we should earnestly pray that we may be enabled, without reserve, to obey his commands, and that we may be enabled, without reserve, to the love of God, and the patience of Christ.
