John.....I would point out that the Apostles had the same abilities as did Jesus. Jesus commissioned them in Marl 16:17-18
"And these signs will accompany those who believe: in my name they will cast out demons; they will speak in new tongues; 18 they will pick up serpents with their hands; and if they drink any deadly poison, it will not hurt them; they will lay their hands on the sick, and they will recover.”
Many miracles were performed by the apostles (2:43). Peter healed the lame man at the Temple (3:7-11). God answered Peter in a miraculous earthquake (4:31). Ananias and Sapphira were slain by the Lord (5:5-10). Signs and wonders continued to be done by the apostles (5:12). Peter healed many from various cities (5:12-16). The prison doors were opened by an angel (5:19). Stephen wrought great wonders and signs (6:8). In Samaria, Philip did great miracles and signs (8:6,7,13).
The big thing that I realized..... Jesus AUTHORIZED and Commanded the disciples to do specific actions... The Disciples were being Obedient when they were healing.... They were doing specifically what they were commanded by Jesus to do....
Our job is to be Obedient... Wherever that leads... Whatever God leads us to do.... Paul gives us examples of what we may be called to do in Ephesians 4.... and it's our job to be Obedient....
So... God calls you to be Obedient -
If He calls you to declare his Healing upon someone... Go do it! They will be Healed!
If God does NOT call you to declare his healing upon someone... Don't.... They won't.
My opinion is that this is where we run into trouble... We substitute "Wishing and Hoping" for "Be Obedient and Seek God's Face" - and we wonder why stuff doesn't happen.....
The deal with Ananias and Sapphira is something different but related in my opinion..... Notice how Peter never does this again...
In my own opinion - God is showing Peter that he has "Official Standing" before God's Throne to Intercede or Not....
Ref back to Matt 18:18 and John 14:13 - this relates to "Official Standing" when God sends you out into a ministry.....
Compare to 2 kings 2:23-24 (Elisha and the bears) and Amos 7: 1-6
When God sends YOU.... He gives YOU the authority that you will need to perform your ministry..... and that includes the Authority to come before the Throne of God to intercede for people in your ministry....
In the incident with Elisha - A couple young kids were bothering him - so he curses at them.... Bears come along and kill them! What's this all about? Well... Elisha is NOW officially THE Prophet of the Lord.... He NOW has standing before the Lord... Notice how Elisha never again curses "Innocents".... He is NOW speaking for the Lord God of Israel - and he needs to watch himself..... God had to teach him a lesson....
Amos 7:1-6.. God issues a bunch of curses and Amos prays, then God relents... Huh? Same thing... As THE Official Prophet of the Lord to Israel - Amos has STANDING before God.... Amos has the right to Intercede for the people he is entrusted with..... In this case - Amos does Intercede for those people - and God relents.... Notice how in Amos 7:10-17 - Amos does NOT intercede for the priest who is slandering him... and the word of God goes forth upon that man and his family....
When God sends YOU... You now have the the Authority to come before His Throne for Those people.... You now have Standing to seek his face pertaining to these things..... Will you Curse them or will you Intercede for them?
