"“Strive to enter in at the strait gate.”— Luke 13:24 . The belated traveler, hurrying to reach the city gate by the going down of the sun, could not turn aside for any attractions by the way. His whole mind was bent on the one purpose of entering the gate. The same intensity of purpose, said Jesus, is required in the Christian life. I have opened to you the glory of character, which is the true glory of My kingdom. It offers you no promise of earthly dominion; yet it is worthy of your supreme desire and effort. I do not call you to battle for the supremacy of the world's great empire, but do not therefore conclude that there is no battle to be fought nor victories to be won. I bid you strive, agonize, to enter into My spiritual kingdom. MB 141"
"Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able."
Ellen White directly references Luke 13:24 in this passage.
"The Christian life is a battle and a march. But the victory to be gained is not won by human power. The field of conflict is the domain of the heart. The battle which we have to fight—the greatest battle that was ever fought by man—is the surrender of self to the will of God, the yielding of the heart to the sovereignty of love. The old nature, born of blood and of the will of the flesh, cannot inherit the kingdom of God. The hereditary tendencies, the former habits, must be given up. MB 141.2"
"For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would."
Both passages discuss the conflict between the flesh and the spirit, and the need to overcome the desires of the flesh to live a Christian life. EGW expands on the idea of surrendering self.
"He who determines to enter the spiritual kingdom will find that all the powers and passions of an unregenerate nature, backed by the forces of the kingdom of darkness, are arrayed against him. Selfishness and pride will make a stand against anything that would show them to be sinful. We cannot, of ourselves, conquer the evil desires and habits that strive for the mastery. We cannot overcome the mighty foe who holds us in his thrall. God alone can give us the victory. He desires us to have the mastery over ourselves, our own will and ways. But He cannot work in us without our consent and co-operation. The divine Spirit works through the faculties and powers given to man. Our energies are required to co-operate with God. MB 141.3"
"For it is God which worketh in you both to will and to do of his good pleasure."
The EGW passage directly reflects the principle in Philippians 2:13, emphasizing that God works in us to will and to do, but also highlighting the need for our cooperation.
"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
Both passages highlight the spiritual battle against evil forces. EGW provides a more detailed description of the internal struggle and the forces arrayed against the individual.
"For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not."
Both passages acknowledge the inherent inability of humans to do good on their own. EGW expands on this by stating that we cannot conquer evil desires and habits by ourselves.
