so much as think of it; He bids us behold and rejoice, and we will not so much as look at it; and yet we complain for want of comfort. It is by _believing_ that we are _filled with joy and peace_, and no longer than we continue our believing. It is _in hope_ the saints _rejoice_, and no longer than they continue hoping. God's Spirit worketh our comforts, by setting our spirits on work upon the promises, and raising our thoughts to the place of our comforts. As you would delight a covetous man by shewing him gold; so God delights his people by leading them, as it were, into heaven, and shewing them himself, and their rest with him. He does not cast in our joys while we are idle, or taken up with other things. He gives the fruits of the earth while we plough, and sow, and weed, and water, and dung, and dress, and with patience expect his blessing; so doth he give the joys of the soul. I entreat thee, reader, in the name of the Lord, and as thou valuest the life of constant joy, and that good conscience, which is a continual feast, to set upon this work seriously, and learn the art of heavenly-mindedness, and thou shalt find the increase an hundred fold, and the benefit abundantly exceed thy labor. But this is the misery of man's nature; though every man naturally hates sorrow, and loves the most merry and joyful life, yet few love the way to joy, or will endure the pains by which it is obtained; they will take the next that comes to hand, and content themselves with earthly pleasures, rather than they will ascend to heaven to seek it; and yet when all is done, they must have it there, or be without it. § 6. (4.) A heart in heaven will be a most excellent preservative against temptation to sin. It will keep the heart well employed. When we are idle, we tempt the Devil to tempt us; as careless persons make thieves. A heart in heaven can reply to the tempter, as Nehemiah did, _I am doing a great work, so that I cannot come_. It hath no leisure to be lustful or wanton, ambitious, or worldly. If you were but busy in your lawful callings, you would not be so ready to hearken to temptations; much less if you were also busy above with God. Would a judge be persuaded to rise from the bench, when he is sitting upon life and death, to go and play with children in the streets? No more will a Christian, when he is taking a survey of his eternal rest, give ear to the alluring charms of Satan. The children of the kingdom should never have time for trifles, especially when they are employed in the affairs of the kingdom; and this employment is one of the saint's chief preservatives from temptations.
