Yes, “there is liberty”. To Paul, It’s all really about the liberty of access. He is building on what he wrote in 2 Corinthians 3:12. Poole said: “A liberty from the yoke of the law, from sin, death, hell; but the liberty which seemeth here to be chiefly intended, is liberty from that blindness and hardness which is upon men’s hearts, until they have received the Holy Spirit.”
For instance, today, we exercise incredible strength of discourse. Boldness is a word that has a place to liberty. Due to the incredible work of the Holy Spirit in us through the new pledge, we have a striking, freed relationship with God. That’s it!!!
