2 Corinthians 13:14
The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, be with you all. Amen.
While the Bible doesn't teach a triune God, we do see a triune system of faith. Let's look at the real trinity of Christianity.
The grace of the Lord Jesus Christ
John 1:17 For the law was given by Moses, but grace and truth came by Jesus Christ.} Jesus Christ is the last Adam, the perfect man who was born of God and was sent to reconcile God's Creation. Grace is God's favor and the free gift of salvation to those who have faith in Jesus Christ. To have faith is to accept Jesus as your Lord and Savior and to believe that he is the Son of God sent by God to atone for your sins.
and the love of God
John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.} God is the Father and the Father alone is All Mighty God. He so loved us that He sent His Son to atone for our sins and to lead us in all truth.
and the communion of the Holy Ghost
1 Corinthians 12:13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.} The Holy Spirit isn't a person or being but is the divine nature and presence of God. The Holy Spirit is a gift of God to those who believe. It is the spirit that joins us in fellowship; We have communion with one another, with God and His son through the Holy Spirit.
The true trinity of Christianity is this:
The love of God, the reconciliation of Christ, and the gift of the Holy Spirit which joins us all.
Through Jesus we go to God and receive the gift.
