The problem wasn’t the manual; I would submit that he hadn’t followed the instructions in the manual.
Similarly, in the Christian walk, we too have a manual; the Bible. The theory is that if we follow the instructions in the manual (the Bible), we have success.
If people are getting into trouble in their lives, we deduct that they must not be following the manual (the Bible). We think that the manual (the Bible) is a step by step instruction for us to follow as though we were putting together a model airplane.
That is why He came to the earth, Emmanuel (or Immanuel):
“Behold, the virgin shall be with child, and bear a Son, and they shall call His name Emmanuel,” which is translated, “God with us.” (Matthew 1:23)
He wants us to DAILY be led by His Holy Spirit:
“However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come.” (John 16:13)
“I say then: Walk in the Spirit, and you shall not fulfill the lust of the flesh.” (Galatians 5:16)
“For as many as are led by the Spirit of God, these are sons of God.” (Romans 8:14)
