The true fear of God is filial love

From the additional notes to Charles Spurgeon's The Treasury of David on Psalm 112

Verse 1. Praise ye the LORD. This exhortation is never given too often; the Lord always deserves praise, we ought always to render it, we are frequently forgetful of it, and it is always well to be stirred up to it. The exhortation is addressed to all thoughtful persons who observe the way and manner of life of men that fear the Lord. If there be any virtue, if there be any praise, the Lord should have all the glory of it, for we are his workmanship. Blessed is the man that feareth the Lord. According to the last verse of Psalm 111, the fear of the Lord is the beginning of wisdom; this man, therefore, has begun to be wise, and wisdom has brought him present happiness, and secured him eternal felicity. Jehovah is so great that he is to be feared and had in reverence of all them that are round about him, and he is at the same time so infinitely good that the fear is sweetened into filial love, and becomes a delightful emotion, by no means engendering bondage. There is a slavish fear which is accursed; but that godly fear which leads to delight in the service of God is infinitely blessed. Jehovah is to be praised both for inspiring men with godly fear and for the blessedness which they enjoy in consequence thereof. We ought to bless God for blessing any man, and especially for setting the seal of his approbation upon the godly. His favour towards the God fearing displays his character and encourages gracious feelings in others, therefore let him be praised. That delighteth greatly in his commandments. The man not only studies the divine precepts and endeavours to observe them, but rejoices to do so: holiness is his happiness, devotion is his delight, truth is his treasure. He rejoices in the precepts of godliness, yea, and delights greatly in them. We have known hypocrites rejoice in the doctrines, but never in the commandments. Ungodly men may in some measure obey the commandments out of fear, but only a gracious man will observe them with delight. Cheerful obedience is the only acceptable obedience; he who obeys reluctantly is disobedient at heart, but he who takes pleasure in the command is truly loyal. If through divine grace we find ourselves described in these two sentences, let us give all the praise to God, for he hath wrought all our works in us, and the dispositions out of which they spring. Let self righteous men praise themselves, but he who has been made righteous by grace renders all the praise to the Lord.
