17:22 And the glory which You gave Me I have given them, that they may be one just as We are one: 23 I in them, and You in Me; that they may be made perfect in one, and that the world may know that You have sent Me, and have loved them as You have loved Me.
Glory - a revelation of God's character. It's not to be quickly passed by that there is a tight link between God's character and oneness. Unbreakable bonds, whether it be between friends, a married couple, or any other bond between people, you will find common factors at the root of all healthy relationships. There is a saying that circulates on Facebook and I've seen it in other places too. "A true friend is someone who knows all your faults and loves you anyway."
Love that is conditional is not love. There are many who argue about God and His love and whether it is conditional or not. Here is the truth. The giving of Jesus to us was an undeniable proclamation of God's unconditional love. Jesus didn't come for some, He came for all. God so loved the world... has no limits or conditions. Jesus' interactions with people from every walk of life and across borders etc... showed His love had no limits or restrictions.
So what's with all the conditions? The conditions without exception lie with us. God so loved the world... that whoever (again no limits) believes in Him will not perish but have everlasting life. Even an atheist will admit the end of this life is death. God is not saying "love me or die". He is saying "I am offering you an alternative because I love you. It is yours for the choosing. The cost is all mine and the benefit is all yours."
The condition is if we want it or not. Love never forces. Freedom is an inseparable component of love. Anyone who restricts it in any way does not love you.
Now back to glory and oneness. Being one with someone can only occur to the degree that the elements of God's character are present in the relationship. This is a universal truth that cannot be changed. Two atheists can have a healthy relationship only if the elements of God's character are present in the relationship.
Bold ideas to be sure but truth nonetheless. Think about it. The only one of the Twelve who left did so of His own choosing. He decides the character of God was not for him and the kingdom of God was not a place he wanted to be. Jesus extended love and mercy and suffered long with Judas. He was stealing money and Jesus did not expose him. He was planting seeds of doubt and discontent and Jesus did not stop him. In fact what happened in Judas is exactly what happened in Satan. Slowly discontent and selfishness were cultivated and coddled until he could no longer abide in the presence of Jesus.
That's definitely not the choice God wants us to make but His love leaves us free to choose and our choices create the future conditions we will experience as a result. I am free to be selfish and arrogant and use people for my own purposes but the resulting conditions will be loneliness, misery, and an inability to trust or be trusted.
Glory embraced produces oneness with God and with others. Glory rejected produces the opposite and the choice lies with us.
The world is right to scratch their heads when they look at the "people of God" and see the traits of Satan.
My favourite author wrote: "When the character of Christ is fully reflected in His people He will come and claim them as His own." This reality will occur. To be a part of it or apart from it remains with us.
