My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous. 2 He is the propitiation for our sins, and not for ours only but also for the sins of the whole world. 3 And by this we know that we have come to know him, if we keep his commandments. 4 Whoever says “I know him” but does not keep his commandments is a liar, and the truth is not in him, 5 but whoever keeps his word, in him truly the love of God is perfected. By this we may know that we are in him: 6 whoever says he abides in him ought to walk in the same way in which he walked. - 1 John 2:1-6
What does it mean to have an advocate? It means we have someone on our side. But more than that, an advocate is an ally, but one who has more knowledge or authority than we do. They plead our case when we cannot. We don’t know the rules of the system. We don’t know the language or the protocols. We might not even know what is wrong with us that we need assistance.
