The resurrection is the insurrection of all fear.
"and what is the exceeding greatness of His power
toward us who believe,
according to the working of His mighty power
which He worked in Christ when He raised Him from the dead
and seated Him at His right hand in the heavenly places,"
Ephesians 1:19-20
Whenever fear, anxiety, or worry arise in your heart and mind, Lord Jesus’ resurrection is your weapon in hand. The same Holy Spirit that raised Him from the dead:
Lives. In. You.
If you have received Christ’s atoning sacrifice for your sins by faith, you are His child. Nope, I know. You and I are so far from perfect that it isn’t funny. Still, His shed bled, that we will remember this Good Friday, was enough. It is still enough.
And now, the Third Person of the Godhead, the Holy Spirit, lives in you. And when fear comes calling, you have Holy Spirit help in the Name of Jesus, to reject it. You may stumble and fall a few times at first, but keeping standing in the truth of His Word. His resurrection power is all you need and you already have it.
"For God has not given us a spirit of fear, but of power and of love and of a sound mind."
2 Timothy 1:7
