From the very beginning, God has existed in and been a part of community with Jesus and the Holy Spirit. We see in the gospel that when Jesus began his ministry, he went and found 12 guys and told them to follow him. Placing them into community. As followers of Jesus, we are brought into biblical community with God, and according to the Bible, there is no part of life that we should be doing on our own.
The Word of God is the primary means by which God changes us. It speaks liberating truth to our enslaved hearts as we read it ourselves and as we speak it to others. How does that happen and how does God reinforce our faith through this grace?
