Do I believe we can do every "God" can...No, but we can do those things that Jesus did and more
My answers are found in the scriptures,
John 14:12 "I tell you the truth, anyone who has faith in me will do what I have been doing. He will do even greater things than these." How is it possible to do greater works than Jesus did? Consider just a few of his miracles. He healed the blind. He made the lame walk. He raised the dead. He exorcized demons. He made the deaf hear. He made the mute talk. He cleansed leprosy and cured fever. He walked on water. He calmed the storm and multiplied food for crowds of 4,000 and 5,000, not including women and children. In other words, Jesus exercised power over nature, demons, disease, and death
Mark 16:16-19 (King James Version)
16He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
17And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
18They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.
19So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God.
So I believe it has to do with "faith" how much faith do you have in order to do these things? If you have faith as small as a mustared seed....
Luke 17:6 (New King James Version)
6 So the Lord said, “If you have faith as a mustard seed, you can say to this mulberry tree, ‘Be pulled up by the roots and be planted in the sea,’ and it would obey you.
