Behold, he cometh with clouds (in His people, filled w His Spirit); and every (spiritual) eye shall see him, and they also which pierced him (Christ died for all/ we ALL pierced Him): and all kindreds of the earth (IN you) shall wail because of him (the battle of flesh vs Spirit). Even so, Amen. Revelation 1:7
There is only one testimony and that is the testimony of Christ. The testimony of Jesus IS the Spirit of prophecy because ALL prophecy is fufilled when a person is born again and Christ in dwells a person.
The testimony of Jesus is what He did on the cross and what He does IN His people in the New Covenant. Drawing them to Himself, and putting His Spirit in them. A born again person IS the Testimony of Jesus. Christ fulfills all things IN His people.
Christ brings His people thru every trial. Thru every fire and every flood. He overcomes this world IN us. He changes us.
Even as the testimony (Spirit) of Christ was confirmed IN you: So that ye come behind in no gift (Christ in you IS the gift); waiting for the coming of our Lord Jesus Christ (ongoing, the overcoming of this world IN you by Christ):
1 Corinthians 1:6-7
Gods people ARE His Testimony. Living epistles. His Witnesses. He is our Temple and we are His Candlesticks. His Bride. His Holy City. His Angels. His Prophets. The leaves on His tree for the healing of the nations. We bare the record of the word (Spirit) of God. We are HIS workmanship. New creations. Complete in Christ.
Seek Jesus with all of your heart for truth and for His Spirit. You must be born again.
