When you are seeking the Lord and His healing you will experience attacks. The enemy does not want you to be restored.

Notice when “the walls of Jerusalem were being restored and the gaps were beginning to be closed, that they became very angry,  and all of them conspired together to come and attack Jerusalem and create confusion. Nevertheless we made our prayer to our God, and because of them we set a watch against them day and night.” Nehemiah 4:7-9

When you are rejoicing always, praying continually and giving thanks in all situations the enemy has no hold (1 Thess 5:16-18).
