Children of God
You may be interested in commentary on Sunday's message - the new covenant and what it means.
Yes, people can and should read the Bible. True believers have God's law in their hearts. God's Spirit provides the power for humans to trust and obey, love God and other people.
In 2 Corinthians 3 verse 6, "the letter kills." Not the law or written Word of God. It is the demands of the law without the Spirit's life and power to fulfill God's will. With the Holy Spirit, the letter no longer kills.
The apostle Paul calls this "the ministry of the Spirit." The Father, Son and Spirit were there at the beginning. While the Son is found in many verses of the Old Testament, He came to life, Son of a virgin. The Holy Spirit also was active, but the shower of fire on 120 believers on Pentecost introduced Him to mankind. And He lives within the hearts of everyone who believes and trusts. All over the world.
All the benefits in Christ come by the Spirit. He mediates Christ's presence and blessings. "Freedom" in the Bible means freedom from condemnation and slavery of sin and the dominion of Satan. We don't get baptized and return to our former ways. The Spirit enters into our "hearts," and we become children of God...if we truly follow up.
Freedom by Christ is not a ticket to cover up evil or justification for conflict. We can experience Christ's nearness. He wants us to be transformed into his likeness, but in this age the transformation is progressive and partial. When Christ returns, we will see him face to face, and our transformation will be complete.
