What does the law have to do with faith?
Paul says in Hebrew 10: 1
Now faith is the substance of things hoped for, the evidence of things not seen. (v.2) For by it the elders obtained a good report. Now by the elder’s faith (belief) in God they obtained a good report.
But how did theses elders show God that they had faith (belief) in him?
Let's see how you can have faith in Jesus as well and have a good report. A man asked Jesus this very question, "...What good thing shall I do that I may have eternal life?", and Jesus replied,
Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments. (Matthew 19:16-19).
The commandments of God are not hard to keep (I John 5:3) and furthermore, they teach us love in the highest degree. If you love Jesus you will
keep his commandments (St. John 14:15). You will not displease the Lord by: Worshipping other gods, having graven images, taking his name in vain, breaking his Sabbath day (which is Saturday not Sunday), or dishonoring your parents. On the other hand, if you love your neighbor as yourself you will not kill him, commit adultery with his spouse, steal from him, falsely accuse him, or covet anything of his.
This is true love, and if obeyed how much better would our world be? This is why Jesus said that the
two greatest commandments are loving the Lord with all your heart, soul, and mind; and loving your neighbor as yourself (Matthew 22:35-40). These two commandments are the foundation of the entire law. Many reject the law, but it is
holy, and the commandment holy, and just, and good (Romans 7:12) even today.
