His main characteristics are: eternal, almighty, omniscient, holy, righteous, faithful, merciful, gracious and jealously loving. God is one, Who surpasses human mind and capacity, but Who can be met through natural and gracious revelation. He revealed Himself in three persons: He is the Father, the Son and the Holy Spirit.
The Father is a perfect and good God, Who is the provider for every being. He can be met through the Son: He revealed the essence of the Father's character, which is love. The Son and the Holy Spirit come from the Father, who are consubstantial with Him, but the Father has priority among them.
He is the image and only Son of the Father. He is eternal God, one with the Father. He was born before every creature; the earthly, heavenly things and beings exist in Him, through Him and for Him. Submitting His will to the Almighty, He made Himself empty and took human nature upon Himself. He was conceived through the Holy Spirit, was born of the Virgin Mary and lived here on earth. He became human-like in everything, except for sin. He was obedient to the Father, during His earthly life and ministry even till His death on the cross. Because of this, the Father resurrected Him from death and crowned Him with glory and honor; made Him Lord over all the work of His hands and seated Him at His right. "He gave Him a name that is above every name, that at the name of Jesus every knee should bow, in Heaven and on earth and under the earth and every tongue confess that Jesus Christ is Lord, to the glory of God the Father." He is the author of the new and eternal covenant and He is the mediator between the Father and the world.
The Holy Spirit
The Holy Spirit is a real person, who comes from the Father and the Son. He came in order to exalt Jesus Christ in the church and to lead every believer to personal communion with the Son, to the knowledge and worship of God. The Holy Spirit is Lord and God. For the sins that are committed against him, there is no forgiveness. He was the one who anointed Jesus of Nazareth, so that He could heal the sick, cast out demons, raise the dead and proclaim the Kingdom of God. He works in humans, in accordance with the Word, repentance and rebirth and makes the gifts of redemption real in the believers. His most important activities are: leading, teaching, counseling and testifying about Jesus.
