Acts 1:4,8 - He commanded them not to leave Jerusalem but to wait for what the Father had promised. But you shall receive power (ability, efficiency, and might) when the Holy Spirit has come upon you.
This power came through an encounter with God.
Some because of their fear of error, have said it's improper to seek for an experience with God.
For decades the church has been guilty of creating doctrine to justify their lack of power, instead of crying out to God until He changed them. The lie they came to believe has given rise to an entire branch of theology that has infected the Body of Christ with a fear of the Holy Spirit. It deceives under the guise of staying undeceived. The word must go forth with power. Power is the realm of the Spirit.
Will you bury your gifts and tell the master when He comes that you were afraid of being wrong?
Matthew 25: 25,26,30 - So I was afraid, and I went and hid your talent in the ground. Here you have what is your own. But the master answered him, "You wicked and lazy and idle servant! And throw the good-for-nothing servant into the outer darkness; there will be weeping and grinding of teeth."
Jude 24: Now unto him that is able to keep you from falling, and to present you faultless before the presence of His glory with exceeding joy.
John 15:7 - If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
JESUS WALKED IN UNION WITH HIS FATHER. WE TOO MUST DO THE SAME WITH HIM. WE ONLY HAVE TRUE SPIRITUAL AUTHORITY TO THE DEGREE THAT WE ARE ABIDING IN HIM. THE ANGELS DO NOT RESPECT US AND THE DEMONS DO NOT OBEY US BECAUSE OF WHO WE ARE, BUT BECAUSE OF WHO IS IN US.
