In reading and rereading this parable I am moved by the Holy Spirit to realize this is very possibly a paradigm relative to the church.
We all seem to recognize who the prodigal son is. He is us. Who among us has not strayed or participated in sin? Our Father not only welcomes us back, He runs to us and falls upon our neck in a compassionate all-accepting, all-forgiving love.
What moves me most personally however, is how I see the older son in so many of us faithful churchgoers/ministers. Too many of us fail to realize the Father when He tells us, "All that I have is yours." What a powerful, dynamic statement our Father makes to us! We find ourselves burdened down in the fields of our churches, working in our own power, and don't see that our Father gives us all that we could ever want for victorious, overcoming life in Him.
Please read Matt 28:18-20 where we are told all authority is given to Jesus and He gives that authority to us! Then, in John 14:1014, we see that the power/authority/rights/abilities He has given us are all to glorify the Father. As joint heirs with Christ, we can hear the Father tell us, "All that I have is yours."
In Matt 6:9-13 we have the clencher! Jesus prays that God's kingdom and will be done on Earth as it is in Heaven. Did the Father refuse this request? Are we not on the Earth, therefor participants in "all that I have is yours." Perhaps we just need to recognize and apply our sonship privileges in God's Kingdom here on Earth. Be blessed.
