There are no disciples without salvation, so it’s crucial that a follower of Jesus intentionally obeys His command to share the gospel with everyone, everywhere.
We have a relationship with Christ in which our number one responsibility is to love him, but we also have a relationship with other believers, and our number one responsibility in that relationship is to love one another.
A disciple of Jesus must be immersed in the Word of God consistently in order to learn His ways. But without the help of the Holy Spirit and our obedience to what God says, this task is of little benefit.
The renewing of our minds can only happen to a Christ follower through the Holy Spirit and the Word of God, but we also have a role in not conforming to the world.
