Hi, Patty, I'm sorry to be so late in answering you, I just found this. The best way I can answer your question about if the kingdom is here now is in what Jesus said "The kingdom is within." Jesus lives in all who believe in him through the Holy Spirit. He is our indwelling comforter and counselor. As we abide in hi, the vine that connects us to heaven, we find new life and we gradually learn how to walk with him and bear good fruit for the glory of God. Yes, the kingdom is in the earth in many mature leaders who have apprehended the fullness of the promises Jesus made to obedient disciples. Quite few churches are really doing the same things Jesus did when he lived.
All we have to do is open our heart to him and allow him to fill us with his spirit. He teaches us how to walk in his word as we do this. Then his kingdom is alive within and soon it flows out to others around us. Personally, I've seen a new life in myself and new salvations in my family as I have set my heart to know Jesus and his word more and more. Does this answer your question?
