"You have not faith and love and confidence in God. If you had, you would trust in Him. You worry yourself out of the arms of Christ, fearing that He will not care for you. Health is sacrificed. God is not glorified in your body and spirit, which are His. There is not a sweet, cheering home influence to soothe and counteract the evil which is predominant in your nature. The high, noble powers of your mind are overpowered by the lower organs; the evil traits of your character are developed. 1T 697.2"
"What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s."
The EGW passage directly echoes the sentiment of 1 Corinthians 6:19-20, particularly the idea that our bodies and spirits belong to God and should be used to glorify Him. The phrase 'God is not glorified in your body and spirit, which are His' is a clear parallel.
"Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed? (For after all these things do the Gentiles seek:) for your heavenly Father knoweth that ye have need of all these things. But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you. Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof."
Both passages address worry and trusting in God's provision. EGW expands on the consequences of not trusting God, which aligns with the principle in Matthew 6:31-34.
