"“Be not anxious.”— Matthew 6:25 , R. V. He who has given you life knows your need of food to sustain it. He who created the body is not unmindful of your need of raiment. Will not He who has bestowed the greater gift bestow also what is needed to make it complete? MB 95"
"Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?"
Ellen White directly references Matthew 6:25 in this passage.
No one can occupy a neutral position; there is no middle class, who neither love God nor serve the enemy of righteousness. Christ is to live in His human agents and work through their faculties and act through their capabilities. Their will must be submitted to His will; they must act with His Spirit. Then it is no more they that live, but Christ that lives in them. He who does not give himself wholly to God is under the control of another power, listening to another voice, whose suggestions are of an entirely different character. Half-and-half service places the human agent on the side of the enemy as a successful ally of the hosts of darkness. When men who claim to be soldiers of Christ engage with the confederacy of Satan, and help along his side, they prove themselves enemies of Christ. They betray sacred trusts. They form a link between Satan and the true soldiers, so that through these agencies the enemy is constantly working to steal away the hearts of Christ's soldiers. MB 94.1…
"No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon."
Both passages emphasize the impossibility of serving two masters (God and something else). The EGW passage elaborates on the implications of divided allegiance.
"I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me."
The EGW passage directly echoes the sentiment of Galatians 2:20, emphasizing Christ living in the believer and the believer's will being submitted to Christ's.
"Jesus pointed His hearers to the birds as they warbled their carols of praise, unencumbered with thoughts of care, for “they sow not, neither do they reap;” and yet the great Father provides for their needs. And He asks, “Are not ye of much more value than they?” R.V. MB 95.3"
"Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?"
The EGW passage directly quotes and references Matthew 6:26, making it a clear and explicit allusion.
"No soul bows low but Jesus knows; For He is with us everywhere, And marks each bitter tear that flows. And He will never, never, never Forsake the soul that trusts Him ever.” MB 95.4"
"The Lord is nigh unto them that are of a broken heart; and saveth such as be of a contrite spirit."
Both passages convey the idea that God is close to those who are suffering and contrite. The EGW passage expresses this through the image of Jesus knowing and marking each tear, while the Psalm speaks of God being near to the brokenhearted.
"The hillsides and the fields were bright with flowers, and, pointing to them in the dewy freshness of the morning, Jesus said, “Consider the lilies of the field, how they grow.” The graceful forms and delicate hues of the plants and flowers may be copied by human skill, but what touch can impart life to even one flower or blade of grass? Every wayside blossom owes its being to the same power that set the starry worlds on high. Through all created things thrills one pulse of life from the great heart of God. The flowers of the field are clothed by His hand in richer robes than have ever graced the forms of earthly kings. And “if God so clothe the grass of the field, which today is, and tomorrow is cast into the oven, shall He not much more clothe you, O ye of little faith?” MB 95.5"
"And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin:"
EGW directly quotes and expands upon Matthew 6:28, making the connection undeniable.
