No, almost everything here is false. We don't have dominion over any of those things.
Jesus had power over life and death, sickness and disease. We don't. We still get sick. We can die young and so can our children.
Jesus never sinned. Those of us who are saved still sin.
(1 John 1:9-10 NIV) If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. {10} If we claim we have not sinned, we make him out to be a liar and his word has no place in our lives.
(1 John 2:1-2 NIV) My dear children, I write this to you so that you will not sin. But if anybody does sin, we have one who speaks to the Father in our defense--Jesus Christ, the Righteous One. {2} He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.
Well it your opinion and I respect it. But as a child of God you have dominion over everything have said in this post, because as a child of God sickness is not your portion neither poverty is. Listen to men of God and they will tell you they have never fall sick before. You can't serve God diligently and have problems. Temptation come and go.
