In every situation, we will only subdue for others the things which we ourselves have overcome.
Trials are meant to do more than just remove the dross from our souls; they actually become the earmarks of specific situations we will subdue for others in the realm of the spirit.
On the road to Damascus, Paul lost his sight for a season. He surrenders to Jesus and finds redemption. While on the road to Cypress (Acts 9:9), Paul speaks to Elymas the sorcerer, who was attempting to pervert the faith. Filled with the Holy Spirit, Paul commands that the sorcerer will lose his sight for a season and that is exactly what happened (Acts 13:9).
Jesus could have never become the perfect High Priest had He not walked in our circumstances. In order to be a high priest that could identify with our condition, He allowed Himself to become familiar with our very struggles and limitations then overcame them through death on the cross (Hebrews 2:17-18). It was after He pushed through the suffering He was able to overcome suffering for us.
There is always a higher purpose in suffering. Once we push through the difficulty not only will we acquire deliverance, but we will be ordained to push back the darkness impeding others.
