Okay, then are you willing to learn?:
Romans 1:18-22 (NKJV)
[SUP]18 [/SUP] For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness,
[SUP]19 [/SUP] because what may be known of God is manifest in them, for God has shown it to them.
[SUP]20 [/SUP] For since the creation of the world His invisible attributes are clearly seen,
being understood by the things that are made,
even His eternal power and Godhead,
so that they are without excuse,
[SUP]21 [/SUP] because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened.
[SUP]22 [/SUP] Professing to be wise, they became fools,
Colossians 1:16-18 (HCSB)
16 For everything was created by Him, in heaven and on earth, the visible and the invisible, whether thrones or dominions or rulers or authorities— all things have been created through Him and for Him.
17 He is before all things, and by Him all things hold together.
18 He is also the head of the body, the church; He is the beginning, the firstborn from the dead, so that He might come to have first place in everything.
Mark 3:28-29 (HCSB)
[SUP]28 [/SUP] I assure you: People will be forgiven for all sins and whatever blasphemies they may blaspheme.
[SUP]29 [/SUP] But whoever blasphemes against the Holy Spirit never has forgiveness, but is guilty of an eternal sin”—
The primary function of the Holy Spirit within the Godhead, is to work on the hearts of human beings to bring us to BELIEVE in the Creator, Jesus Christ. One does not have to KNOW IS NAME, but one certainly has to personally KNOW THE CREATOR. TO REJECT WHAT THE HOLY SPIRIT IS TRYING TO GET ONE TO BELIEVE, IS BLASPHEMING THE WORK OF THE HOLY SPIRIT, AND THEREFORE IS THAT ETERNAL SIN.
Old Testament Saints have the same faith as we have.
Romans 4:3-5 (HCSB)
[SUP]3 [/SUP] For what does the Scripture say? Abraham believed God, and it was credited to him for righteousness.
[SUP]4 [/SUP] Now to the one who works, pay is not considered as a gift, but as something owed.
[SUP]5 [/SUP] But to the one who does not work, but believes on Him who declares the ungodly to be righteous, his faith is credited for righteousness.
Old Testament Saints BELIEVED the Creator would send a Messiah.
New Testament Saints BELIEVED the Creator did send a Messiah.
IT IS THE SAME FAITH, TWO FOLDS, ONE FLOCK, WITH ONE SHEPHERD.
John 10:14-16 (HCSB)
[SUP]14 [/SUP] “I am the good shepherd. I know My own sheep, and they know Me,
[SUP]15 [/SUP] as the Father knows Me, and I know the Father. I lay down My life for the sheep.
[SUP]16 [/SUP] But I have other sheep that are not of this fold; I must bring them also, and they will listen to My voice. Then there will be one flock, one shepherd.
REMEMBER He has not yet died, and the beginning of the CHURCH is considered the Day of Pentecost. He is talking to Old Testament Saints that BELIEVE He is the Messiah that the Creator has sent. He revealed to His followers that HE IS THE CREATOR via the Feeding of the 5000 and the Feeding of the 4000. THEREFORE the CHURCH is the "other sheep that are not of this fold."
