5. Have a close relationship with Jesus. Know the Lord
This comes out of praying and walking in the light and reading the Bible. If you do these things, they you will be in relationship with Jesus. You will know Him, recognize His voice and His leading.
Remember the 7 sons of the Jewish High Priest who tried to cast a demon out of a man?
Now there were seven sons of Sceva, a Jewish chief priest, doing this. But the evil spirit responded and said to them, “I recognize Jesus, and I know of Paul, but who are you?” And the man in whom was the evil spirit, pounced on them and subdued all of them and overpowered them, so that they fled out of that house naked and wounded. Acts 19:14-16
It's not enough to shout out the name of "Jesus". You have to be in relationship with Him!
6. Be constantly filled with the Holy Spirit
Ask the Holy Spirit to fill you each morning and don't do anything that would grieve Him (such as purposeful sin). Listen to Him when He convicts you and repent immediately. The Holy Spirit can be a great friend to you. He can interpret Scripture for you, guide you, teach you, warn you, and nudge you when you need nudging. The Holy Spirit is the power cord that links you to Jesus. Stay plugged in!
