Love is the only attribute which God hath acted to the utmost. We have never seen the utmost of His power, what God can do, but we have seen the utmost of His love: He hath found a ransom for lost souls (Job 33:24).
Enjoy all things for God by using all for Him. Those riches, honors, interests, and friends which are clogs upon the heels of others, let them be as springs to you to raise you heavenward. Let your souls be winged with those very enjoyments wherewith the wings of others are pinioned, and that which is fuel to their worldly lusts, let it be as fuel to feed and nourish your spiritual love. To use what we have for God is the only way not to abuse it; this is one way of enjoying all for God, to use all for Him.
Luxury is living in pleasure. God allows us to use pleasures, but not to live in them; to take delights, but not that they should take us. To live always at the full is but a wanton luxury.
Pleasures are like a substance in the pursuit, but clouds in the enjoyment. Pleasure is a beautiful harlot sitting in her chariot whose four wheels are pride, gluttony, lust, and idleness; the two horses are prosperity and abundance; the two drivers are idleness and security; her attendants and followers are guilt, grief, late repentance (if any), and oft death and ruin.
Some know but to know. Some know to be known. Some know to practice what they know. Now to know but to know, that is curiosity. To know to be known, that is vainglory. But to know to practice what we know, that is gospel duty. This makes a man a complete Christian; the other without this makes a man almost, and yet but almost a Christian.
Heaven is a freedom from all evil both of sin and suffering, so that a name in heaven entitles us to a blessed redemption from all evil. There is no sin there. Grace weakens sin, but it is glory that abolishes it. Old Adam shall there be put off, never be put on again. The Lord Christ will present His church in that day, "faultless before the presence of his glory with exceeding joy" (Jude 24). There is no affliction there. Sin and sorrow came in together, and they shall go out together.
Many men are changed in a moral sense, and one may say they are become new men, but they are in heart and nature the same men still. They are not changed in a spiritual and supernatural sense, and therefore it cannot be said of them they are become new creatures. Restraining grace may cause a moral change, but it is renewing grace that must cause a saving change. Now many are under restraining grace, and so changed morally, that are not under the power of renewing grace, and so changed savingly.
If you would know whether your names are written in heaven, satisfy yourselves in this: that the call of God hath took effectual hold of your hearts. Hath it brought your souls off from every thing below Christ wholly to follow Christ? It is said when Christ called Peter and Andrew, they presently "left their nets, and followed him" (Matt. 4:18–20). Every man hath his nets, somewhat that his soul is entangled in, till the call of God take hold of him. Can you now, with Peter, when God calls, lay aside your nets to follow Him?
