15:18 Why is my pain perpetual, and my wound incurable, [which] refuseth to be healed? wilt thou be altogether to me {r} as a liar, [and as] waters [that] fail?
(r) And have not assisted me according to the promise? In which it appears that in the saints of God is imperfection of faith, which through impatience is often assailed as in Jer 20:7.
15:18 Why - Jeremiah, though a great prophet, was (as Elijah) a man subject to like passions with other men.
15:15-21 It is matter of comfort that we have a God, to whose knowledge of all things we may appeal. Jeremiah pleads with God for mercy and relief against his enemies, persecutors, and slanderers. It will be a comfort to God's ministers, when men despise them, if they have the testimony of their own consciences. But he complains, that he found little pleasure in his work. Some good people lose much of the pleasantness of religion by the fretfulness and uneasiness of their natural temper, which they indulge. The Lord called the prophet to cease from his distrust, and to return to his work. If he attended thereto, he might be assured the Lord would deliver him from his enemies. Those who are with God, and faithful to him, he will deliver from trouble or carry through it. Many things appear frightful, which do not at all hurt a real believer in Christ.
