What and who is God, Jesus and Holy Spirit?

God the Father holds a pivotal role as the originator of all creation, the maintainer of the universe, and the source of wisdom and justice. He initiates salvation by sending His Son, Jesus Christ, to redeem humanity. John 3:16 says, "For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life." The Father's love and authority are evident in His provision, protection, and guidance of believers.
Jesus Christ, the Son, is the second Person of the Trinity. Fully God and fully man, He was sent by the Father to redeem humanity. Conceived by the Holy Spirit and born of the Virgin Mary, Jesus lived a sinless life, died for our sins, and rose again, securing our salvation (1 Corinthians 15:3-4)
The Holy Spirit is the third Person of the Trinity, fully God, and equal with the Father and the Son. He is a personal being, not just a force. The Holy Spirit has always existed with the Father and the Son. The Holy Spirit helps us understand Jesus, comforts us, guides us, and convicts us of our need for God. When we believe in Jesus, the Holy Spirit lives in us, transforming our hearts and minds. He also gives us spiritual gifts to serve others and produces qualities like love and joy in our lives. The Holy Spirit is essential for understanding and experiencing God’s presence and work in our lives.

What is the bible?

The Bible is the written Word of God and thus the ultimate set of guiding principles governing all areas of life for the people of God. Through these writings, God communicates his will, his laws, his nature, and his saving purpose to humanity.
The Bible is a compilation of 66 books and letters written by more than 40 authors during a period of approximately 1,500 years. The original text of the Bible was communicated in just three languages: Hebrew, koine or common Greek, and Aramaic. The Old Testament was written for the most part in Hebrew, with a small percentage in Aramaic. The New Testament was written in Greek.
