I have heard most of my Christian life not to concern myself with the Old Testament. It’s the law and we aren’t under the anymore. Guess what? If you sin, what happens to you? You fall under the consequence of the law. In Romans 3:23 and 6:23, the wages of sin is death. The old testament completes the picture of Jesus. It’s as relevant to us today as it was to the Christians of the first century. They only heard scriptures from the old testament about Jesus. We stand upon the law and prophets as our firm foundation. In Matthew 22:36-40, Jesus said there are 2 great commandments, to love God with all we are and to love our neighbors as ourselves. Deuteronomy and Leviticus. Every scripture has meaning for us. If we only believe and trust God. Abraham was justified by faith and so are we.
