"In many cases the Testimonies are fully received, the sin and indulgence broken off, and reformation at once commences in harmony with the light God has given. In other instances sinful indulgences are cherished, the Testimonies are rejected, and many excuses which are untrue are offered to others as the reason for refusing to receive them. The true reason is not given. It is a lack of moral courage—a will, strengthened and controlled by the Spirit of God, to renounce hurtful habits. 4T 32.1"
"Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof."
Both passages address the principle of not letting sin control one's actions. EGW speaks of renouncing hurtful habits, while Romans 6:12 urges not letting sin reign in the mortal body. The core principle of resisting sin is shared.
"It is not an easy matter to overcome an established taste for narcotics and stimulants. In the name of Christ alone can this great victory be gained. He overcame in behalf of man in the long fast of nearly six weeks in the wilderness of temptation. He sympathizes with the weakness of man. His love for fallen man was so great that He made an infinite sacrifice that He might reach him in his degradation and through His divine power finally elevate him to His throne. But it rests with man whether Christ shall accomplish for him that which He is fully able to do. 4T 32.2"
"Then was Jesus led up of the Spirit into the wilderness to be tempted of the devil. And when he had fasted forty days and forty nights, he was afterward an hungred. And when the tempter came to him, he said, If thou be the Son of God, command that these stones be made bread. But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God. Then the devil taketh him up into the holy city, and setteth him on a pinnacle of the temple, And saith unto him, If thou be the Son of God, cast thyself down: for it is written, He shall give his angels charge concerning thee: and in their hands they shall bear thee up, lest at any time thou dash thy foot against a stone. Jesus said unto him, It is written again, Thou shalt not tempt the Lord thy God. Again, the devil taketh him up into an exceeding high mountain, and sheweth him all the kingdoms of the world, and the glory of them; And saith unto him, All these things will I give thee, if thou wilt fall down and worship me. Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve. Then the devil leaveth him, and, behold, angels came and ministered unto him."
The EGW passage directly references Christ's temptation in the wilderness and connects it to overcoming personal struggles. The mention of the fast and temptation makes the connection more than just a general theme.
"Will man take hold of divine power, and with determination and perseverance resist Satan, as Christ has given him example in His conflict with the foe in the wilderness of temptation? God cannot save man against his will from the power of Satan's artifices. Man must work with his human power, aided by the divine power of Christ, to resist and to conquer at any cost to himself. In short, man must overcome as Christ overcame. And then, through the victory that it is his privilege to gain by the all-powerful name of Jesus, he may become an heir of God and joint heir with Jesus Christ. This could not be the case if Christ alone did all the overcoming. Man must do his part; he must be victor on his own account, through the strength and grace that Christ gives him. Man must be a co-worker with Christ in the labor of overcoming, and then he will be partaker with Christ of His glory. 4T 32.3"
"For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith."
The EGW passage echoes the principle of overcoming through faith, drawing a parallel between Christ's victory and the believer's victory, which aligns with the core message of 1 John 5:4.
