You cannot give away what you do not have. The majority of my life what I thought was love was actually dependency, needing a person to give me what I thought I needed, instead of getting it from God. I was not loving others, but needing them. When God is the central source of my life I can truly love another human being freely because I believe “Love does not demand its own way”. 
If I go to God to be my source for love I find it in abundance, then can I enter relationships with something to give away. This is what true intrinsic motivation to love looks like, it comes from a place of total freedom… I love you just because I do—not expecting anything in return. Love that is given conditionally so that I get something in return is not true love but manipulation. This is being selfish and it is not about loving you well, but all about me.
When I feel lonely, abandoned, isolated, wounded or hurt my motivation becomes tested. It is in my pain that my true motivation is revealed. If my motivation is fear driven then when I am in the pressure of a crisis and feeling all those difficult feelings, I’m going to slip into my codependency. I continue to learn in my own struggles the unique and powerful difference between the extrinsic and intrinsic motivation.
What I have learned about myself is that I am really driven by the need of your approval and acceptance to make me feel lovable. I can be easily dependent on your approval and acceptance at the expense of being dishonest with you and myself. If God is my primary source for love then he is whom I seek for my value. Seeking fulfillment outside of God gets me in trouble. The pattern is I give to get which is functioning from a deficit and it is very dysfunctional.
If the truth will set me free, then the truth is nothing can separate me from the love of Christ. I must accept this truth and trust God will do for me what I cannot do for myself. God must become everything to me first, and then I can reach towards others with the gift of love, instead of the manipulation of neediness.
Growing up, I always knew that when I went home someone would be there to love me no matter what. Like that love, Christ’s love for me is unconditional and I do not have to earn it. Daily, God is teaching me to love, transforming and pursuing me until I come home to him.
