Our duty is to wait, when God stays his longest before fulfilling his promise

           Second.  When God stays long before he makes payment of the promise, then it is the believer’s duty to wait for it.  ‘Though it tarry, wait for it,’ Hab. 2:3. He is speaking there of the good of the promise, which God intended to perform in the appointed time; and because it might tarry longer than their hasty hearts would, he bids them wait for it.  As one that promiseth to come to a friend’s house sends him word to sit up for him, though he tarry later than or­dinary, for he will come at last assuredly.  This is hard work indeed!  What! wait? When we have stayed so long, and no sight of God’s coming after this prayer, and that sermon!  So many long looks given at the window of his ordinances and providences, and no tidings to be heard of his approach in mercy and comfort to my soul; and after this, still am I bid wait? This is wearisome work.  True, to flesh and blood it is; yea, weak faith is oft out of breath, and prone to sit down, or turn back, when it hath gone long to meet God in the returns of his mercy, and misseth of him; and therefore the apostle ushers in his duty with an affectionate prayer.  ‘The Lord direct your hearts into the love of God, and into the patient waiting for Christ,’ II Thes. 3:5.  He had laid down a strong ground of consolation for them in the preceding chapter, in that they were ‘chosen to salvation,’ and ‘called by the gospel to the obtaining of the glory of our Lord Jesus Christ,’ II Thes. 2:13, 14, and assured them that God, who is ‘faithful,’ would ‘stablish them, and keep them from evil,’ II Thes. 3:3.  He means [this] so as they should not miscarry, and at last fall short of the glory promised; but, being sensible how difficult a work it was for them amidst their own present weaknesses, the apostasies of others, and the assaults of Satan upon themselves, to hold fast the assurance of their hope unto the end, he turns himself from them to speak to God for them.  ‘The Lord direct your hearts.’  And, as if he had said, it is a way you will never find, a work you will never be able to do of yourselves—thus to wait patiently till Christ come, and bring the full reward of the promise with him; the Lord therefore direct your hearts into it.  And Moses, it seems, before he ascended the mount, had a fear and jealousy of what afterward proved too true, that the Israelites' unbelieving hearts would not have the patience to wait for his return, when he should stay some while with God there out of their sight; to prevent which, he gave express command before he went up that they should tarry there for him, Ex 14:14. Indeed, a duty more contrary than this of waiting quietly and silently on God, bear our manners, and lackey after us, before we do what he commands: but if the promise comes not galloping full speed to us, we think it will never be at us.

           Question.  But why doth God, when he hath made a promise, make his people wait so long?

           Answer.  I shall answer this question by asking another. Why doth God make any promise at all to his creature?  This may be well asked, considering how free God was from owing any such kindness to his creature; till, by the mere good pleasure of his will, he put himself into bonds, and made himself, by his promise, a debtor to his elect.  And this proves the former question to be saucy and over-bold.  As if some great rich man should make a poor beggar that is a stranger to him his heir, and when he tells him this, he should ask, ‘But why must I stay so long for it?’  Truly, any time is too soon for him to receive a mercy from God that thinks God's time in sending it too late.  This hasty spirit is as grievous to God as his stay can be to us.  And no wonder God takes it so hei­nously, if we consider the bitter root that bears it.

           First. It proceeds from a selfishness of spirit, whereby we prefer our own content and satisfaction before the glory of God, and this becomes not a gra­cious soul.  Our comfort flows in by the performance of the promise, but the revenue of God's honour is paid into him by our humble waiting on him in the interval between the promise and the performance, and is the main end why he forbears the paying it in hastily.  Jacob served seven years for Rachel; and God sure may better make us wait, before the promise is given in to our embraces by the full accomplishment of it.  ‘For ye have need of patience, that, after ye have done the will of God, ye might receive the prom­ise,’ Heb. 10:36.  It is very fit the master should dine before the man.  And if he would not like a servant that would think much to stay so long from his meal as is required at his hands for waiting at his master’s table, how much more must God dislike the rudeness of our impatient spirits, that would be set at our meal, and have our turn served in the comfort of the prom­ise, before he hath the honour of our waiting on him!

           Second.  It proceeds from deep ingratitude; and this is a sin odious to God and man.  ‘They soon for­gat his works; they waited not for his counsel,’ Ps. 106:13.  God was not behindhand with his people.  It was not so long since he had given them an experi­ment of his power and truth.  He had but newly lent them his hand, and led them dry‑shod through a sea, with which they seemed to be much confirmed in their faith, and enlarged in their acknowledgments, when they came safe to shore: ‘then believed they his words; they sang his praise,’ Ps. 106:12.  One would have thought that God's credit now would have gone for a great sum with them ever after.  But it proved nothing so.  They dare not trust God with so much as their bill of fare—what they shall eat and drink; and therefore it is said, ‘they waited not for his counsel, but lusted exceedingly in the wilderness.’  That is, they prevented the wisdom and providence of God, which would have provided well for them, if they could but have stayed to see how God would have spread their table for them.  And why all this haste? ‘They forgat his works.’  They had lost the thankful sense of what was past, and therefore cannot wait for what was to come.
