"God regards us as His children. He has redeemed us out of the careless world and has chosen us to become members of the royal family, sons and daughters of the heavenly King. He invites us to trust in Him with a trust deeper and stronger than that of a child in his earthly father. Parents love their children, but the love of God is larger, broader, deeper, than human love can possibly be. It is immeasurable. Then if earthly parents know how to give good gifts to their children, how much more shall our Father in heaven give the Holy Spirit to those who ask Him? COL 142.1"
"Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not."
The EGW passage directly references the concept of being called 'sons and daughters of God' and the Father's love, which is a clear allusion to 1 John 3:1.
"And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together."
Both passages discuss the idea of believers being children of God and therefore heirs. The EGW passage speaks of being members of the royal family, which aligns with the concept of being heirs of God.
"Christ's lessons in regard to prayer should be carefully considered. There is a divine science in prayer, and His illustration brings to view principles that all need to understand. He shows what is the true spirit of prayer, He teaches the necessity of perseverance in presenting our requests to God, and assures us of His willingness to hear and answer prayer. COL 142.2"
"Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you:"
The EGW passage speaks of Christ's lessons on prayer and the necessity of perseverance, which directly relates to the teaching in Matthew 7:7 about asking, seeking, and knocking.
"Our prayers are not to be a selfish asking, merely for our own benefit. We are to ask that we may give. The principle of Christ's life must be the principle of our lives. “For their sakes,” He said, speaking of His disciples, “I sanctify Myself, that they also might be sanctified.” John 17:19 . The same devotion, the same self-sacrifice, the same subjection to the claims of the word of God, that were manifest in Christ, must be seen in His servants. Our mission to the world is not to serve or please ourselves; we are to glorify God by co-operating with Him to save sinners. We are to ask blessings from God that we may communicate to others. The capacity for receiving is preserved only by imparting. We cannot continue to receive heavenly treasure without communicating to those around us. COL 142.3"
"And for their sakes I sanctify myself, that they also might be sanctified through the truth."
Ellen White directly references John 17:19 in this passage.
