Psalms 34:4 (NKJV) I sought the LORD, and He heard me, And delivered me from all my fears.
If Jesus already delivered us from everything we could ever be afraid of, and yet we still fear something, that fear cannot be based in reality. We are seeing something incorrectly if we are in fear. Both cannot be true at the same time. Jesus cannot have delivered you from all your fears already at the cross and you still have a valid fear. True, people can still fear things, but it is no longer a valid fear. It’s merely something about the cross they aren’t realizing right now.
The perspective from which you are viewing your situation cannot be true if it is causing you fear, because Jesus delivered you from everything you could be afraid of. We only fear because we’re not thinking in reality. When our mind is perfected in the reality of what Jesus has done, there isn’t any room for fear.
1 John 4:18 (NKJV)
There is no fear in love but perfect love [or rather, “perfected knowledge of love”] casts out fear… but he who fears has not been made perfect in love.
