Those who chose to accept this New Covenant on the day of Pentecost when Peter preached the first Gospel lesson (remember Gospel means “Good News”), followed the instructions of the apostles.
And they devoted themselves to the apostles’ teaching and the fellowship, to the breaking of bread and the prayers (Acts 2:42–43).
Jesus had given the apostles this authority and responsibility.
These things I have spoken to you while I am still with you. But the Helper, the Holy Spirit, whom the Father will send in my name, He will teach you all things and bring to your remembrance all that I have said to you (John 14:25–26).
During the first century, the apostles would guide the process by which the New Testament (which means the same as the New Covenant) would be written. The Holy Spirit of God guided the apostles miraculously as they recorded the teachings of Jesus—Scriptures preserved for all time. Today, the Bible is composed of two main parts:
- The Old Testament
- The New Testament
We can trust that what God wants us to know has been preserved for us in the Bible.
All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work (2 Timothy 3:16–17).
