Now the Spirit of God came on Azariah the son of Oded, and he went out to meet Asa and said to him, “Listen to me, Asa, and all Judah and Benjamin: the Lord is with you when you are with Him. And if you seek Him, He will let you find Him; but if you forsake Him, He will forsake you.
2 Chronicles 15:1-2
The most amazing, life-changing, power-giving, soul-enhancing relationship in the universe — that would be the relationship we can have with God.
Think about it. If God exists, if God made the cosmos, if God made the possibility of you, if you really are his offspring, then acknowledging him, knowing him — that would seem to be super important. If he is all-powerful, and he is all good, then a relationship with him would be more important than any other relationship.
But check this out. A relationship with God is something God has left up to us. According to 2 Chronicles 15: 1-2, those who don’t want him, don’t find him. Those who are not with him, he is not with them. As Pascal has said, God has revealed himself just well enoough that those who want him find him, those who don’t miss him.
Powerful God has decided not to tyrannize us, not to force himself on us, not to demand a relationship with us. A relationship with God — certainly he has initiated this — but there is something core in it that is up to us. Power is in our hands because power has made it that way. Those who reject God because they don’t want to give over control of their lives to God are unaware of the control that he has put in their own hands. God does not want to control us; God wants to empower us to be in control of ourselves, to choose well, to live well and to do good.
If we are with God, then he is with us to empower us to the best life possible. If we are not with God; he is not with us, and we are left with the weakness of our own limits. 2 Chronicles 15:1-2 is a clear statement of human responsibility for the nature of our relationship with God. We have been told the truth by Azariah the son of Oded, just as Asa and Judah and Benjamin were told.
The next move is most definitely, significantly and consequentially up to us.
Thrive! 
I remember our conversation on the morning of June 29th in your sitting area, and we were talking about this principle in the context of C.S. Lewis’ Screwtape Letters.
