From the Word
Do you not know that you are God’s temple and that God’s Spirit dwells in you?
1 Corinthians 3:16, RSV
What a glorious, noble, loving, and precious guest and house companion man receives, God the Father and the Son and certainly with them also the Holy Spirit. This is certainly a sublime, beautiful promise, and one of the precious and exceeding great promises granted unto us poor, miserable sinners, that we through them should become partakers of the divine nature, and should be so highly honored as not only to be loved of God through Christ Jesus and to enjoy his favor and grace, but should even have the Lord himself dwelling completely in us.
Where else should God dwell? Those self-constituted saints, in their own estimation excellent, high and great, are much too proud, much too high, wise and holy. They have passed up through and far above heaven, so that they could not be his habitation upon earth, although they boast of being the only Church and people of God. Though they appear in all the pomp and glory and ornament of their self-made holiness, yet God does not do them the honor to look at them. He is found in the humble huts of the poor and despised, who fear and believe the Word of Christ and would gladly become Christians, but who feel that they are very unholy and unworthy sinners. “They are a temple of the living God.”
These things are accomplished in this way: in addition to the grace by which a man begins to believe and to hold fast to the Word, God also rules in man through his divine power and agency, so that he constantly grows more and more enlightened, becomes richer and stronger in spiritual understanding and wisdom, and better fitted to understand all matters of doctrine and practice. He further makes daily progress in life and good works, becomes eventually a kind, gentle, patient man, ready to serve every one with doctrine, advice, comfort, and gifts; is useful to God and man; through him and because of him men and countries are benefited; in short, he is a man through whom God speaks, in whom he lives and works. His tongue is God’s tongue, his hand is God’s hand, and his word is God’s Word. His doctrine and confession as a Christian are not of men, but of Christ, whose Word he has and holds.
