From the Word
4 I give thanks to God always for you because of the grace of God which was given you in Christ Jesus, 5 that in every way you were enriched in him with all speech and all knowledge — 6 even as the testimony to Christ was confirmed among you — 7 so that you are not lacking in any spiritual gift, as you wait for the revealing of our Lord Jesus Christ; 8 who will sustain you to the end, guiltless in the day of our Lord Jesus Christ. 9 God is faithful, by whom you were called into the fellowship of his Son, Jesus Christ our Lord.
1 Corinthians 1:4–9, RSV
What Paul terms being enriched “in all utterance”—which, in the exalted spiritual meaning of the words, bears on life everlasting—is having the comfort of faith in Christ and of invocation and prayer. “Enriched in all knowledge” means having true conception and right judgment in all things of our physical life and in all our earthly relations. All things that a Christian should know and should possess are comprehended in these two terms. These blessings are gifts and treasures indescribably great. He who will contrast them with the destitution of our former condition cannot but be joyful and thankful.
The Christian has indeed inestimable treasures. In the first place he has the testimony of the Word of God, which is the word of eternal grace and comfort, that he has a right and true conception of Baptism, the Lord’s Supper, the Commandments and the Creed. In addition he has the sure refuge of God’s promise to deliver us from every trouble in which we shall call upon him, and to give us, as he promised by the prophet Zechariah, the Spirit of grace and of prayer. And the Christian, by virtue of his enlightened understanding, can wisely discern what are good works and what callings are pleasing to God; on the other hand, his judgments are equally true as to unprofitable and vain works and false services. Formerly we had not this wholesome knowledge. We knew not what we believed, or how we prayed and lived. We sought comfort and salvation in self-devised trivialities, in penances, confessions and satisfactions, in self-righteous works of monkery and in obedience to the commands of the Pope. We believed such works to be fully satisfactory and, indeed, the only things that were holy; the pursuits of common Christians we considered worldly and dangerous. In contrast to this darkness, consider the priceless and to-be-cherished blessing of knowing with certainty wherein the heart is to take comfort, how to seek help in distress and how to conduct oneself in one’s own station. Truly we should now render to God heartfelt thanks for the great favor and blessing of restored light and understanding in Scripture and the right conception of doctrinal matters.
