Gal 3:5 (NIV)
Does God give you his Spirit and work miracles among you because you observe the law or because you believe what you heard?
Old covenant believing by observing the law does not bring us to a place of miracles but condemnation. If we expect miracles to happen through our own effort to please God, then it is not believing but barter trading.
What have you heard? Have you heard of the finished work of Christ 2000 years ago and how He wrought for us on the cross sonship, inheritance of His blessings...and cancel all the curses...and plenty more?
Rejoice, only believe in His finished work. We can't add anything more when work is already finished. Only believe.
