“But this I confess unto thee, that after the way which they call heresy, so worship I the God of my fathers, believing all things which are written in the law and in the prophets: and have hope toward God, which they themselves also allow, that there shall be a resurrection of the dead, both of the just and unjust.” Acts 24:14-15 (KJB)
The apostle Paul is being tried for his faith in Jesus Christ, the crucified, buried, and risen One who forever lives and reigns as King of all kings, and Lord of all lords.
His beliefs are based on the Old Testament; the Law and the Prophets. That does not exclude the history or the wisdom books either. There are many Christians today who want to say and teach that the Old Testament is not needed. It is the only Bible, the only Scripture that they had. It is the only Scripture which Jesus knew and read. It is the only Scripture which Matthew, Mark, Luke, and John relied on. It is the Scripture which John the Baptist preached.
Preach and teach the New Testament Yes; but do not neglect the Old.
I have been spending this year staying with the New Testament. I felt I needed to get more familiar with the words of Jesus, the apostles, and including the apostle Paul. I will not shun, neither neglect the Old Testament though. Without the Old there would be no New.
Someone has said, “The Old Testament is the New Testament concealed; and the New Testament is the Old Testament revealed.” A great thought.
There is a resurrection of the dead; both of the just and the unjust. Which resurrection will you be part of? We are only made just by the death, burial, and resurrection of Jesus Christ.
