Just doing a simple search of the word "excellent" and its cognates in a few dozen Puritan books turned up 8,623 instances of the word, chiefly in reference to the manifold excellencies of God.
In his work, Christ Altogether Lovely, Puritan divine John Flavel (1630-1691) applies the truth that he is lovely in his person, in his offices, and in his relations to the believer. Using Song of Songs 5:16 as his text, Flavel concludes:
1. Is Jesus Christ altogether lovely? Then I beseech you set your souls upon this lovely Jesus. I am sure such an object as has been here represented, would compel love from the coldest breast and hardest heart. Away with those empty nothings, away with this vain deceitful world, which deserves not the thousandth part of the love you give it. Let all stand aside and give way to Christ. O if only you knew his worth and excellency, what he is in himself, what he has done for you, and deserved from you, you would need no arguments of mine to persuade you to love him!
2. Esteem nothing lovely except as it is enjoyed in Christ, or used for the sake of Christ . Love nothing for itself, love nothing separate from Jesus Christ. In two things we all sin in love of created things. We sin in the excess of our affections, loving them above the proper value of mere created things. We also sin in the inordinacy of our affections, that is to say we give our love for created things a priority it should never have.
3. Let us all be humbled for the corruption of our hearts that are so eager in their affections for vanities and trifles and so hard to be persuaded to the love of Christ, who is altogether lovely. O how many pour out streams of love and delight upon the vain and empty created thing; while no arguments can draw forth one drop of love from their stubborn and unbelieving hearts to Jesus Christ! I have read of one Joannes Mollius, who was observed to go often alone, and weep bitterly; and being pressed by a friend to know the cause of his troubles, said "O! it grieves me that I cannot bring this heart of mine to love Jesus Christ more fervently."
4. Represent Christ to the world as he is, by your behaviour towards him . Is he altogether lovely? Let all the world see and know that he is so, by your delights in him and communion with him; zeal for him, and readiness to part with any other lovely thing upon his account. Proclaim his excellencies to the world, as the spouse did in these verses. Persuade them how much your beloved is better than any other beloved. Show his glorious excellencies as you speak of him; hold him forth to others, as he is in himself: altogether lovely. See that you "walk worthy of him unto all well pleasing," Col. 1:10. "Show forth the praises of Christ," 1 Pet. 2:19 . Let not that "worthy name be blasphemed through you," James 2:7 . He is glorious in himself, and he is sure to put glory upon you; take heed that you do not put shame and dishonours upon him; he has committed his honour to you, do not betray that trust.
Never be ashamed to be counted as a Christian : he is altogether lovely; he can never be a shame to you; it will be your great sin to be ashamed of him. Some men glory in their shame; do not let yourself be ashamed of your glory. If you will be ashamed of Christ now, he will be ashamed of you when he shall appear in his own glory, and the glory of all his holy angels. Be ashamed of nothing but sin; and among other sins, be ashamed especially for this sin, that you have no more love for him who is altogether lovely.
6. Be willing to leave every thing that is lovely upon earth , in order that you may be with the altogether lovely Lord Jesus Christ in heaven. Lift up your voices with the bride, Rev. 20:20 "Come Lord Jesus, come quickly." It is true, you must pass through the pangs of death into his intimacy and enjoyment; but surely it is worth suffering much more than that to be with this lovely Jesus. "The Lord direct your hearts into the love of God, and the patient waiting for Jesus Christ," 2 Thes. 3:5.
7. Let the loveliness of Christ draw all men to him . Is loveliness in the creature so attractive? And can the transcendent loveliness of Christ draw none? O the blindness of man! If you see no beauty in Christ that causes you to desire him, it is because the god of this world has blinded your minds.
8. Strive to be Christ-like, if ever you would be lovely in the eyes of God and man . Certainly, my brethren, it is only the Spirit of Christ within you, and the beauty of Christ upon you, which can make you lovely persons. The more you resemble him in holiness, the more will you show of true excellence and loveliness; and the more frequent and spiritual your communication and communion with Christ is, the more of the beauty and loveliness of Christ will be stamped upon your spirits, changing you into the same image, from glory to glory. Amen.
J.I. Packer said it well when he asked the question: "Why do we need the Puritans?"
What could these zealots give us that we need, it is asked. The answer, in one word, is maturity. Maturity is a compound of wisdom, goodwill, resilience, and creativity. The Puritans exemplified maturity; we don’t. We are spiritual dwarfs. A much-travelled leader, a native American (be it said), has declared that he finds North American Protestantism, man-centered, manipulative, success-oriented, self-indulgent and sentimental, as it blatantly is, to be 3,000 miles wide and half an inch deep. The Puritans, by contrast, as a body were giants. They were great souls serving a great God. In them clear-headed passion and warm-hearted compassion combined. Visionary and practical, idealistic and realistic too, goal-oriented and methodical, they were great believers, great hopers, great doers, and great sufferers. But their sufferings, both sides of the ocean (in old England from the authorities and in New England from the elements), seasoned and ripened them till they gained a stature that was nothing short of heroic. Ease and luxury, such as our affluence brings us today, do not make for maturity; hardship and struggle however do, and the Puritans’ battles against the spiritual and climatic wildernesses in which God set them produced a virility of character, undaunted and unsinkable, rising above discouragement and fears, for which the true precedents and models are men like Moses, and Nehemiah, and Peter after Pentecost, and the apostle Paul.

In a world of trite, overly commercialized, market-tested trivial pursuits passing for Christian books, Puritans like Flavel are a God-send to the parched and thirsty soul! Drink deeply and often!
