Ephesians 2:17,18 “Now all of us can come to the Father through the same Holy Spirit because of what Christ has done for us. So now you Gentiles are no longer strangers and foreigners. You are citizens along with all of God’s holy people. You are members of God’s family.”
“Because of what Christ has done for us…” In the Old Testament, if the High Priest didn’t do the right thing in the temple, he died immediately. So it was with fear and trembling that they entered and performed their duties in the Most Holy Place. It had to be perfect! And the people would wait also with great fear because if the high priest didn’t do things right and he died, it meant that their year wouldn’t go well for them. But our High Priest is Jesus Who did everything perfectly, and now we have access into the Father’s Presence at any time. We don’t have to fear that we won’t be accepted or that we will die if we make mistakes.
Also, the Gentiles had no rights in the Jewish community. While God promised protection and provision for His own, Gentiles could not have any of that. But Jesus made a way for us non Jews to be a part of His kingdom, of His family. Now, we have the right to ask for protection, for provision, for healing, etc. whatever it is you need, you can ask God, your Father. You belong to His family. And it is all because of Jesus Who made the way for you!
