“I feel burned out, and I don’t want to pray!”

What does the Revelation 22 warning about adding or subtracting mean? Is the “sanctification” in Hebrews 10:14 progressive or finished? How does Hebrews 10:10 factor in? I feel burned out and I have lost some of my desire to pray for others. What should I do?

How exactly do we “walk by the Spirit”?

What is the difference between discipleship and sonship? How do we know we’re walking by the Spirit? Does the Father actually “take away” branches that don’t bear enough fruit?
