Mathew chapter 21 verses 19 to 22.
Where Jesus cursed the fig tree then told His disciples they too could do things like that.
So did He mean in faith believing, a Christian could in theory curse someone to wither and die away?
If so, it means the power of Christ can be used to destroy life as well as to heal or restore life. I never have understood what the fig tree did wrong anyway!
A saint can put a curse on someone for I have did it many times cursing people until they experienced pain, and torment, driving them mad, and numbing their emotions causing them mental delusions, and physical agony the likes that have never been experienced except by the most dictatorship rulers, and making them crippled both mentally, and physically, to where they could not function but be curled up in a ball until they perished from off the earth.
Of course a Christian cannot curse a person for they are not to harm a person which they are to love their enemies, and feed, and clothe their enemies.
Mat 21:18 Now in the morning as he returned into the city, he hungered.
Mat 21:19 And when he saw a fig tree in the way, he came to it, and found nothing thereon, but leaves only, and said unto it, Let no fruit grow on thee henceforward for ever. And presently the fig tree withered away.
Mat 21:20 And when the disciples saw it, they marvelled, saying, How soon is the fig tree withered away!
Mat 21:21 Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this which is done to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done.
Mat 21:22 And all things, whatsoever ye shall ask in prayer, believing, ye shall receive.
This is about a fig tree parable, and has nothing to do with cursing people.
The Christian lifestyle is to not hurt anyone, and want the best for them no matter how they treat you.
