"Through the right exercise of the will, an entire change may be made in your life. By yielding up your will to Christ, you ally yourself with the power that is above all principalities and powers."
"I can do all things through Christ which strengtheneth me."
Both address the transformation that comes through union with Christ. Paul declares the outcome (I can do all things); Ellen White describes the mechanism (yielding the will to access divine power).
"A life in Christ is a life of restfulness. There may be no ecstasy of feeling, but there should be an abiding, peaceful trust. Your hope is not in yourself; it is in Christ. Your weakness is united to His strength, your ignorance to His wisdom, your frailty to His enduring might. So you are not to look to yourself, not to let the mind dwell upon self, but look to Christ. Let the mind dwell upon His love, upon the beauty, the perfection, of His character. Christ in His self-denial, Christ in His humiliation, Christ in His purity and holiness, Christ in His matchless love—this is the subject for the soul's contemplation. It is by loving Him, copying Him, depending wholly upon Him, that you are to be transformed into His likeness. SC 70.2"
"Come unto me, all ye that labour and are heavy laden, and I will give you rest."
The EGW passage directly expands on the concept of finding rest in Christ, echoing the invitation in Matthew 11:28. The 'restfulness' and 'peaceful trust' are direct results of coming to Christ as described in Matthew.
"And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me."
The EGW passage speaks of weakness being united to Christ's strength, which is a clear parallel to 2 Corinthians 12:9 where God's strength is made perfect in weakness. The idea of relying on Christ's power instead of one's own is central to both passages.
"Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things."
While not a direct quote or allusion, the EGW passage's emphasis on dwelling on the beauty and perfection of Christ's character aligns with Philippians 4:8's call to think on things that are true, honest, just, pure, lovely, and of good report. Both passages encourage focusing the mind on positive and virtuous things.
