Jesus changed the spiritual situation on earth. By his death on the cross, he destroyed the authority of spiritual powers of evil. He provided full spiritual protection for those who choose to follow him. He gave the gift of spiritual discernment, so that his people can discern evil spirits wherever they are working. We no longer need to rely on blanket rules for spiritual protections. Instead, we can discern evil spirits wherever they are working, and if we put on the spiritual armour, they cannot touch us.
Jesus had perfect spiritual protection, so he did not have to be careful to avoid situations where he might pick up and evil spirit. They could not touch him, so he went boldly into the world confronting evil spirits and bringing them under the authority of God. For example, When Jesus saw a person with skin disease, he did not need to avoid him, because he could discern if there was an evil spirit at work, and if there was, he had the authority to force it to leave. Therefore, he reached out and touched the leper who asked him for healing (Mark 1:42-44).
We should follow Jesus example. We have spiritual protection in him, so we no longer need to hide from places and situations where we might come into contact with evil spirits. Instead, we should discern their work and confront them and drive them away.
