10% Christianity

I once heard an old prophet of God say that church attendance constitutes about 10% of Christianity. Some people think they have done their 'Christian' duty when they have given their tithe - their 10%. They've gone to church and given their tithe...so, that's about it, right? I don't think so. Is it not true that to be saved one must give one's heart to the Lord? The Apostle Paul said he was a bond slave to Christ, meaning he belonged entirely to the Lord. Does God require any less for us today? Does He have all your heart or just 10%? Is the other 90% of your income yours to do as you please? If you want a legalistic Christianity, I guess it will suffice. But consider this. Do you really want to be a bond slave to Him or just a part time Christian, say 10%? Or how about 50%? Or even 90%? No, if we really want to be radical let's just give Him our whole heart and completely surrender or bodies as a living sacrifice. Today's nominal Christianity is a shadow of the life God has in mind for you. "All to Jesus I surrender, all to Him I freely give." I dare say if we would try it, our lives would be radically changed, and so would others who are looking to find the genuine article.
