Zechariah 4:6 (NKJV)
"So he answered and said to me: This is the word of the Lord to Zerubbabel: Not by might nor by power, but by My Spirit, Says the Lord of host."
THE EVIDENCE OF THE HOLY SPIRIT IS POWER:
Acts 1:8 (AMP)
"But you shall receive power (ability, efficiency, and might) when the Holy Spirit has come upon you, and you shall be My witnesses in Jerusalem and all Judea and Samaria and to the ends (the very bounds) of the earth."
THE EVIDENCE OF THE HOLY SPIRIT IS TRUTH:
John 16:13-14 (AMP)
"But when He, the Spirit of Truth (the Truth-giving Spirit) comes, He will guide you into all the Truth (the whole, full Truth). For He will not speak His own message [on His own authority]; but He will tell whatever He hears [from the Father; He will give the message that has been given to Him], and He will announce and declare to you the things that are to come [that will happen in the future].14 He will honor and glorify Me, because He will take of (receive, draw upon) what is Mine and will reveal (declare, disclose, transmit) it to you."
