I have not read the other comments regarding this and I wanted to write what comes to me through the Spirit. I wrote and re-wrote learning more and more and refreshing old beliefs.
Here is how it is revealed to me.
God created Jesus long ago, so Jesus has always been. He has existed through new testimony prophecy, John the Baptist and in old testament prophecy and through scripture. He proved Himself to be God by example. He illuminated the Spirit of God and revealed God desires for us and to us and still does even now as you seek Him. Jesus was sent as the example, as the way out for those who believed in God and wanted a way out to stand up under. He was and is and will always be, the Healer, the Teacher, The Faithful, the Flawless, The Powerful, The Humble, The Meek, The Seeker, The Deliver, The Forgiver, The Sacrifice, The Redeemer and whatever else is good and perfect like God's will for us. He is the epitome of peace, love, kindness, gentleness, goodness and self-discipline because He was, by God's grace and mercy the image of God and He is of God's Spirit, created by God's Spirit, Dwelling richly in us might I add through the gift He promised us, the Holy Spirit. Sharing Himself, revealing Himself and Giving Himself to us freely through having only to believe. Jesus said, to sum it up, two of the greatest commandments are...Love thy Lord your God with all your heart, mind, soul and strength and treat each other as you would yourself. How were we to love a God we knew so little about, who could change at a moments thought because He is the Great I AM, after all, He is the One who could make us or break us, who could be heard in the word and through prophets, but not be seen? But, He is Greater than our thoughts isn't He. He gave us Christ, so we would have the way out to stand up under. We now had what God planned for us so long ago. Jesus!!! That's how we get to know Him. Christ Jesus was the true Spirit of God. Through Jesus He showed us that we are to be like Him, forgiving, loving, guiding, humble, disciplined, faithful, seeking, honoring, obeying, peaceful, kind, gentle, fruitful, honest, teachers, healers, prayerful, discerning, sacrificing, serving, surrendering, delivers of the word and so much more. He keeps simply showing us His will and His ways. How, through His Spirit which through our faith He freely has given us.
Okay, to sum it up:
God loves us so much He sent His Son..."biological" son in human terminology, thus making Jesus God, but He also sent Jesus as human...making Jesus into a child of God too. We become children of God as humans for our faith...So Jesus showed us that as a human He was a child of God (a son, the kind of son or child of a Father we are to become through our faith) and as a God, He was God's Holy and Righteous Son as He created Him to be. So to me Son, shows that Jesus was like John describes, God's one and only begotten Son and He was everything Holy and Righteous as God is, but He was also human which God the Father isn't, showing us that as a human we are able to inherit the Spirit of God through our faith, making it possible for God the Father's Spirit to exist in a human body.
I see it this way:
God created Jesus to be human and to be Him, thus making Him a "biological Son" as a God and because He is also human He is a child of God in the sense that He served Father by doing His will. Both ways were achieved because Jesus is the Spirit of God, created in the Spirit, to reveal His Spirit and to give His Spirit. Jesus as a human showed us that we too as humans can be a child of God.
