Christian, it is right to say to God "All I have is Yours", because it is. But, the heart of God revealed in Christ responds back "All I have is yours!" This is the love of God revealed, and glorious mystery of the Gospel, that we are children of God, co-heirs with Christ, of everything that belongs to our Father. As sons and daughters of God, like in our natural life with our fathers, in a sense all they have is in essence ours, whether or not it has been inherited yet, and likewise with our children, all we have is theirs, because they are our remembrance, our heritage, apart of us. It is not that you are losing all things surrendering them to God, but you are truly discovering the beauty of the oneness in ownership with the Creator, that He has given you in Christ, and you see the beauty of living life freed of the love of things like money and power, like Christ taught us.

So let no one boast in men. For all things are yours, whether Paul or Apollos or Cephas or the world or life or death or the present or the future—all are yours, and you are Christ's, and Christ is God's.  1 Corinthians 3:21-23 (ESV)
