Understand what I say [1] He added this, not on account of the obscurity of the comparisons which he has set forth, but that Timothy himself might ponder, how much more excellent is the warfare under the direction of Christ, and how much more abundant the reward; for, when we have studied it incessantly, we scarcely arrive at a full knowledge of it. The Lord give thee understanding in all things The prayer, which now follows, is added by way of correction. Because our minds do not easily rise to that "incorruptible crown" (1-Corinthians 9:25) of the life to come, [2] Paul betakes himself to God, to "give understanding" to Timothy. And hence we infer, that not less are we taught in vain, if the Lord do not open our understandings, than the commandments would be given in vain, if he did not impart strength to perform them. For who could have taught better than Paul? And yet, in order that he may teach with any advantage, he prays that God may train his disciple.

1 - "Enten ce que je di, of, Considere." -- "Understand what I say, or, Consider what I say.

2 - "De la vie eternelle." -- "Of eternal life."

Consider what I say; - see the notes at 1-Timothy 4:15. The sense is "Think of the condition of the soldier, and the principles on which he is enlisted; think of the aspirant for the crown in the Grecian games; think of the farmer, patiently toiling in the prospect of the distant harvest; and then go to your work with a similar spirit." These things are worth attention. When the minister of the gospel thinks of his hardships, of his struggles against an evil world, and of his arduous and constant discouraging toil, let him think of the soldier, of the man who struggles for this world's honors, and of the patient farmer - AND be content. How patiently do they bear all, and yet for what inferior rewards!
And the Lord give thee understanding in all things - Enable you to see the force of these considerations, and to apply them to your own case. Such are often the discouragements of the ministry; so prone is the mind to despondency, that we need the help of the Lord to enable us to apply the most obvious considerations, and to derive support from the most plain and simple truths and promises.

Consider what I say - Apply my metaphors and similitudes in a proper manner.
And the Lord give thee understanding - But instead of δῳη, may he give, ACDEFG, several others, besides versions and fathers, have δωσει he will give. Consider thou properly, and God will give thee a proper understanding of all things that concern thy own peace, and the peace and prosperity of his Church. Think as well as read.

(5) Consider what I say; and the Lord give thee understanding in all things.
(5) All these things cannot be understood, and much less practised, unless we ask of God and he gives us understanding.

Consider what I say,.... The advice given by the apostle to Timothy, to be strong in the grace of Christ; to commit the doctrines of the Gospel to faithful and able men; and to endure hardness for the sake of it: as also the characters which he bore as a soldier, a runner in a race, or a wrestler, and an husbandman; and therefore must not expect ease and rest, but war, difficulties, toil, and labour; and likewise under what titles Christ was to be regarded; as his General, and Captain of salvation, that commanded him; as the righteous Judge, that held the prize and crown for which he was running; and the chief Shepherd, who would reward all his labours; and moreover, the glorious reward of grace itself, he might expect, as eternal life, when he had fought the good fight the crown of righteousness, when he had finished his course, or run his race; and a crown of glory that fades not away, when the chief Shepherd should appear: and by putting him upon the consideration of these things, he suggests, that they were matters of moment and importance, and would be of great use to him in assisting and encouraging his faith, amidst all trials and exercises; and whereas they were expressed in figurative terms, taken from the soldier, the runner in a race, and the husbandman, they might not at first view be so easy to be understood; and therefore he would have him think of them, and meditate upon them, and weigh them in his mind; as well as he would not have him take things upon trust from him, but examine them whether they were right or not; though he doubted not but that they would be found to be agreeable to the standard of truth: wherefore he prays as follows,
and the Lord give thee understanding in all things; in all the above things, and in all others; in all the doctrines and mysteries of grace, and in all the rules of conduct in life. No man has of himself an understanding in spiritual things; this is the gift of God; and where it is given there is need of an increase of it, and always of such a prayer for it. The Alexandrian copy, Vulgate Latin, and Arabic versions, read, "the Lord will give thee", &c, and so the words are a promise, an encouragement to Timothy, to consider well of these things; for he might assure himself, that, in so doing, God would give him more understanding in them.

Consider the force of the illustrations I have given from the soldier, the contender in the games, and the husbandmen, as applying to thyself in thy ministry.
and the Lord give, &c.--The oldest manuscripts read, "for the Lord will give thee understanding." Thou canst understand my meaning so as personally to apply it to thyself; for the Lord will give thee understanding when thou seekest it from Him "in all things." Not intellectual perception, but personal appropriation of the truths metaphorically expressed, was what he needed to be given him by the Lord.

Consider what I say. Reflect, and take in its meaning.
Remember. This is spoken for encouragement in suffering.
That Jesus Christ of the seed of David. Even as the prophets had predicted that he should be.
Was raised from the dead. He suffered, died, but was not holden of death, and was exalted.
My gospel. The gospel I preach everywhere.
Wherein I suffer trouble. For this gospel. For it I am now a prisoner as an evil doer.
The word of God is not bound. Its great preacher was, but the Word could not be. It was being preached abroad by thousands of tongues.
Therefore I endure. Since the work goes on, I endure cheerfully.
For the elect's sakes. All came upon him on account of his devotion to the church. He suffered that others, God's chosen ones, might obtain salvation.
