If your financial situation was different where a high income wage can secure your family's future by having a two or more bedroom home then it is most likely that you will win your son back, especially if you have a partner to make things easier financially. Spiritual-wise, just like Jesus in your faithful heart, your son's faith is in your heart. I believe that your son is well looked after financially by his new parents so that he can get the best out of school education without any financial family problems. Your attorney is to keep an eye on this couple and if they fail to secure your son's future for a much longer than brief moment in time then the evidence of their financial weakness will end the boy's future with them which means that your son your will be in your hands if your financial situation is secure. Another possibility even though you might not like it, is to support the parents if they are both Christian, since being a Christian is being an ambassador of Christ, where the Word of God can bring supernatural justice and peace in the hearts of our local or global community, where the spiritual war of Satan never seems to end inside our minds and bodies, as well as the poverty, crime and war in our world. Jesus is our victorious savior and there is no time-stopping magic wand for Satan who wants to prevent Christ's second coming soon in our future. When Jesus returns we will all be living in peace as brothers and sisters of Christ with brand new glorious minds and bodies of Christ, where health, youth and failure-proof intelligence will not make us stumble with our walk with Jesus, or even become accident-prone. May your Christian faith stay strong in the hearts of your son and his parents - that's if they are Christian who will be brothers and sisters of Christ in our futuristic most massive community-built city: the Kingdom of God on a new Earth when Jesus returns Rev 21:2 .:*:.
