"There is need that much time be spent in secret prayer, in close communion with God. Thus only can victories be won. Eternal vigilance is the price of safety. CT 258.1"
"But the end of all things is at hand: be ye therefore sober, and watch unto prayer."
Both passages stress the importance of prayer and watchfulness. EGW's 'eternal vigilance is the price of safety' aligns with the call to 'be sober, and watch unto prayer'.
"The Lord's covenant is with His saints. Everyone is to discern his weak points of character and guard against them with vigor. Those who have been buried with Christ in baptism, and been raised in the likeness of His resurrection, have pledged themselves to live in newness of life. “If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. Set your affection on things above, not on things on the earth. For ye are dead, and your life is hid with Christ in God. When Christ, who is our life, shall appear, then shall ye also appear with Him in glory.” Colossians 3:1-4 . CT 258.2"
"If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. Set your affection on things above, not on things on the earth. For ye are dead, and your life is hid with Christ in God."
EGW directly quotes Colossians 3:1-4.
"If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. Set your affection on things above, not on things on the earth. For ye are dead, and your life is hid with Christ in God. When Christ, who is our life, shall appear, then shall ye also appear with him in glory."
Ellen White directly references Colossians 3:1-4 in this passage.
"***** The Christian youth should be trained to bear responsibilities with brave heart and willing hand. He should learn to encounter the trials of life with patience and fortitude, to follow maxims of worth, and to confirm himself in habits that will enable him to win the victor's crown. There is no time more favorable in which to acknowledge the power of Christ's saving grace and to be controlled by the principles of the divine law. CT 258.3 ***** Wherever in His providence God has placed you, He will keep you. “As thy days, so shall thy strength be.” Deuteronomy 33:25 . CT 258.4"
"Thy shoes shall be iron and brass; and as thy days, so shall thy strength be."
Ellen White directly references Deuteronomy 33:25 in this passage.
"And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible."
While the first part of the EGW quote relates more to 1 Corinthians 9:25, the latter part directly quotes Deuteronomy 33:25. The overall theme is about strength and endurance in the Christian life.
