God is Trinity as the Father, Son, and Holy Spirit. While the Bible never uses the word Trinity, it clearly reveals one God in three Persons. The triune God works in perfect harmony from the beginning to the completion of our eternal salvation. There is election by God the Father, redemption by God the Son, and regeneration by God the Holy Spirit.
God the Father chose to save us by grace through His Son Jesus (Ephesians 1:4-6). God the Son came to reveal the fullness of God's grace (John 1:14). He died for our sins on the cross. He is risen from the dead to save all who believe the gospel (1 Corinthians 15:1-4). God the Holy Spirit, also known as the Spirit of grace, applies our eternal salvation (Ephesians 1:13-14).
You may draw a triangle on paper to illustrate the Trinity. It is one triangle with three distinct points. So, there is one God in three distinct persons as Father, Son, and Holy Spirit.
We experience the Trinity of God in prayer. We pray to God our Father, in the name of God the Son, through the presence and power of God the Holy Spirit.
Baptism is a public testimony to the Trinity of God. Jesus commanded us to baptize believers in the name of the Father, Son, and Holy Spirit (Matthew 28:19).
