The entire Holy Bible is the true and inspired Word of God. 2 Timothy 3:16
"For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them." Ephesians 2:8-10
Jesus Christ is the Son of God and no one comes to the Father except through faith in Him. John 3:16, John 14:6
God wants all people to be saved and to come to the knowledge of the truth. 1 Timothy 2:3
God the Father, God the Son, and God the Holy Spirit. The Holy Trinity is three persons and yet one God. Matthew 28:19
To share our joy in Christ's Salvation, that is based on Scripture alone, through God's Grace alone, we are saved by Faith alone.
Glory to God in the Highest!
