"Therefore he is able to save completely those who come to God through him, because he always lives to intercede for them. Such a high priest meets our need—one who is holy, blameless, pure, set apart from sinners, exalted above the heavens." - Hebrews 7:25-26
Lawyers are those who speak to the court on our behalf. Some are fairly dependable and some are just interested in their fee. Yet, it is recommended that we have an advocate to protect our legal interests. I have had so many requests to recommend a "good" lawyer that I've lost count. Thankfully, when it comes to the court of heaven, I can recommend an excellent lawyer to intercede with perfection.
Yes, priests are like lawyers. In the Old Testament they spoke to God on behalf of the people. Today we have one high priest who speaks on our behalf... his name is Jesus. There is no better intercessor for our souls, for he is "holy, blameless, pure, set apart from sinners". Since he is able to "save completely", we can say that he has never lost a case. Jesus is the best lawyer that money can't buy. (He represents his clients "pro bono")
Why be represented before God by another sinner? Why try to represent yourself? We all need a high priest that "meets our need" perfectly because he is perfect. Jesus always lives to intercede for you my friend, so give your case to him. He alone is able to "save completely those who come to God through him".
