2 Corinthians 3:17 Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom.
The law brings bondage. Rule-keeping is grueling and not productive. Real freedom doesn’t come from doing what the law says, but from God. He has set us free by His grace and forgiveness.
We can search around for peace and joy and happiness, but we’ll only find them in Christ because only His completed work on the cross can bring us the forgiveness we so desperately need. The Holy Spirit works in us to bring about contentment and joy and they’re only accessible because Jesus chose to come to the earth and take on our sin and put His righteousness onto us. This is why we are free, we have the righteousness of Christ. God looks down on us and sees His sons and daughters and not the sinners that we are because we’re clothed in Christ. Freedom is experiencing God’s love in Christ. The Holy Spirit enables us to experience it.
