4 I tell you, My friends, do not dread and be afraid of those who kill the body and after that have nothing more that they can do.
5 But I will warn you whom you should fear: fear Him Who, after killing, has power to hurl into hell (Gehenna); yes, I say to you, fear Him!
Luke 12:4-5 AMPC
Fear of the Lord
Jesus our Lord, is teaching us to fear God. This type of fear is an actual fear, to be afraid. In the context of this Scripture, Jesus commands us to not be afraid of those who kill the body and after that have nothing more that they can do. We should NOT fear anyone who tries to harm us. Usually, when someones' life is in danger they have a fear for their life and will try to defend their life. Jesus says, "Do Not Be Afraid".
He then warns us who we need to be afraid of. He says, "fear Him, who after killing, has power to cast into Hell; Yes, I say to you fear Him." Why does Jesus want us to be afraid of God?
The Bible teaches us that the fear of the Lord is the beginning of knowledge (Proverbs 1:7).
Also, the fear of the Lord will help keep us from sinning against God. We NEED to be afraid of sinning or doing wrong against God. It is a GOOD fear to have. In Romans 3:18 it talks about how the evil doers have no fear of God.
Some people will try to remove the fear of the Lord because they say we are not to fear God, it is uncomfortable. The Bible teaches us how the early church lived.
"31 Then had the churches rest throughout all Judaea and Galilee and Samaria, and were edified; and walking in the fear of the Lord, and in the comfort of the Holy Ghost, were multiplied."
Acts 9:31 KJV
They lived in the Fear of the Lord AND the comfort of the Holy Spirit.
The reason why they try to get rid of the fear of the Lord is because they are lacking the comfort of the Holy Spirit.
Embrace the fear of the Lord and also walk in the comfort of the Holy Spirit!
