Bible truth is that God knew from the beginning of time that He would manifest Himself in the flesh as Jesus Christ to be crucified, buried, and resurrected to give us the Gospel of Jesus Christ to obey by obeying Acts 2:38 in order that we have the opportunity to be reconciled to God and spend eternity with Him who is seated on the throne of God:
In the beginning was the Word, and the Word was with God, and the Word was God (John 1:1) .... And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father) full of grace and truth (John 1:14).
And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory (1 Timothy 3:16).
Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures (1 Corinthians 15:1-4).
Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do? Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost (Acts 2:37,38).
And to you who are troubled rest with us, when the Lord Jesus shall be revealed from heaven with his mighty angels, In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ (2 Thessalonians 1:7-8).
Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God (Hebrews 12:2).
The Apostle Paul expressed this Bible truth in Ephesians, Chapter 1. Paul said that God knew before the "foundation of the world" that He would reveal Himself as Jesus Christ, to save us from our sinful nature by giving us the Gospel to obey. Obeying the gospel, that is being born again by obeying Acts 2:38, that is, having repented, having your sins remitted through baptism in Jesus' name, being filled with the Holy Ghost with the evidence of speaking in tongues, and living a life that is fully turned to Jesus Christ, is the only way that one can be "holy and without blame before Him in love":
Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ: According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love (Ephesians 1:3-4).
By the grace of God, we are enabled to obey the gospel, so that we can become His sons and daughters and be accepted by Him:
Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, To the praise of the glory of his grace, wherein he hath made us accepted in the beloved (Ephesians 1:5-6).
The Apostle Paul makes it abundantly clear that the "He", "His" and "Him" that he refers to in the above scriptures is Jesus Christ, God who came in the flesh revealing the mystery of His will; and will come again at the dispensation of the fullness of time, the second coming:
In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace; Wherein he hath abounded toward us in all wisdom and prudence; Having made known unto us the mystery of his will, according to his good pleasure which he hath purposed in himself: That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him (Ephesians 1:7-10).
The Apostle Paul describes Bible truth, as the "word of truth" as being the gospel of our salvation:
In whom also we have obtained an inheritance, being predestinated according to the purpose of him who worketh all things after the counsel of his own will: That we should be to the praise of his glory, who first trusted in Christ. In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that Holy Spirit of promise, Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory (Ephesians 1:11-14).
And He said to them, You are from beneath; I am from above. You are of this world; I am not of this world. Therefore I said to you that you will die in your sins; for if you do not believe that I am He, you will die in your sins (John 8:23-24 NKJV).
and we must be born again, born of water and of Spirit,
Jesus answered and said to him, Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God. Nicodemus said to Him, How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born? Jesus answered, Most assuredly, I say to you,unless one is born of water and the Spirit, he cannot enter the kingdom of God (John 3:3-5 NKJV).
Bible truth is that to be reconciled to God, to spend eternity with Him, we must be born again by obeying the Gospel of Jesus Christ by obeying Acts 2:38. There is no other way to heaven! Hallelujah!
