JESUS didn't just pick anyone who wanted to follow HIM and that's one way to affirm that HE had a concept and plan HE was working by (Mark 5: 18 - 20). In addition to that final point, I believe we follow JESUS by preaching to others about JESUS.
Because Pharaoh did not know the LORD, when the LORD said, “let there be…” he said, “why should there be?” all those who question GOD to put off the flame speaking to them do not know the LORD. Then again, they do not want to know the Lord. If so, they wish, by influence the enemy of their souls, to perish from lack of knowledge.
