The father of lies cannot separate us from Jesus
Romans 8:38-39
For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, 39 nor height nor depth, nor any other created thing,shall be able to separate us from the love of God which is in Christ Jesus our Lord.
But
Cor:
4The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel that displays the glory of Christ, who is the image of God.
19 Then the disciples came to Jesus in private and asked, “Why couldn’t we drive it out?”
20 He replied, “Because you have so little faith. Truly I tell you, if you have faith as small as a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.”
Note how it says "the valley of the shadow of death - not the valley of death. The enemy is but a shadow. he does not have the ability to create. We do. And if you read in Job, you will see that God always places a limit on what satan can do.
We are complete in Christ - victorious and overcomers. Christ gave Himself so that we would again have dominion. Do NOT for a second give that back to satan.
