Do you think there is sufficient sound argument to show that The Father is Jehovah and that he remains the God and Father of Jesus?
Without question Jehovah is the Father of Jesus Christ, for on Nisan 14, 33 AD, Jesus died. This means that Jesus was no longer alive; he was dead. But on Nisan 16, 33 AD, a miracle was performed by God in His using His holy spirit to beget Jesus as His spiritual son, so that by His giving life back to Jesus on this occasion, Jehovah became Jesus' Father in the same way that God became Adam's father when he begot Adam as His earthly son by giving him life. (Luke 3:38) The holy spirit is God's reproductive seed that caused Jesus to become God's spirit-begotten son and since Jehovah is responsible for begetting or regenerating the life in Jesus after his death, this is proof that Jesus is God's son (1 John 3:9)
Just as the Bible speaks of Isaac as being Abraham's "only-begotten son," so that Abraham became Isaac's begetter, or father, likewise the Bible also speaks of Jesus as being Jehovah's "only-begotten Son, " because Jehovah became Jesus' Begetter, or Father. (Hebrews 11:17; 1 John 4:9) Jesus became the mediator that reconciled and made peace between two parties, between God on one hand and men on the other hand, proving that Jesus is not God, but a separate entity. (1 Timothy 2:5; Romans 5:10) Some 20 years after Jesus' resurrection, the apostle Paul refers to "God our Father and the Lord Jesus Christ" and he calls Jesus Christ "Lord to the glory of God the Father" (Romans 1:7; 1 Corinthians 1:3; 2 Corinthians 1:2; Galatians 1:3; Ephesians 1:2; Philippians 1:2; 2:12), and so does the apostle John near the end of the first century AD, in 96 AD in referring to Jehovah as "my God" (Revelation 3:2), and in 98 AD in referring to Jesus as "the Son of the Father" (2 John 3).
I hope you find this helpful.
Why not be at peace with your opinion and simply pray for the other person.. Do not go on judging or reviling... It only serves to bring out the worst in us all... It is a division (not the only one either), that is all it is and it will not be settled until Jesus returns. We as Xians are not to seek division but rather unity-- unity in believing Jesus is the Messiah, he completed earthly course and worthy of being King, for us to love God with all our heart, to love others as we love ourself and await his return as faithful servants bearing witness through our lives, words and deeds.
If one is not serving God, of what profit would it be for that person to pray for someone else, since Jehovah, "the Hearer of Prayer" doesn't listen to the prayers of those who are not His servants and of those who are not seeking Him (Psalm 65:2; Hebrews 11:6)? The Bible makes clear that only those calling on the name of Jehovah will be saved, but God only hears the prayers of those that pray to Him in Jesus' name. (Joel 2:32; John 14:6; 15:16)
It's true that all of God's prophets foretold that the Messiah, a Savior raised up by God, would rule a kingdom that would bring changes to the world (Daniel 2:44; 7:13, 14), and Jesus is that Messiah, that Savior and that King, but prayers from anyone having doubts and lacking faith will simply not receive a hearing from God, and their prayers are in vain no matter how much one feels he or she demonstrates neighbor love or claims to love God with his or her whole heart, soul, mind and strength, for if one is not doing the will of the Father, one's good deeds and words in living one's life in accord with one's own will, rather than God's, will be in vain. Absolutely no such persons will be recognized by Jesus as being his followers, and their prayers will never reach God's ears. (Matthew 7:21-23; Hebrews 3:12; James 1:6-8) The prayers of the wicked become a sin, while the prayers of the righteous God does hear. (Psalm 109:7; Proverbs 15:29)
[W]hat difference does it make if the first year it was officially taught was 325 CE? The teaching about the Great Crowd of Other Sheep was not taught until 1935 CE, and the teaching about 1914 CE was not taught until the late 1800's.
I don't see the nexus to your question here, considering that 1914 AD and 1935 AD were years when certain prophetic features from the Bible underwent fulfillment, but in 325 AD came a teaching that totally perverted what the Bible teaches about God and Christ. Hopefully, you'll have a different attitude about the Trinity and will have embraced Bible truth before the foretold great tribulation begins. (John 8:32)
