Apostle Paul advises the believers in the churches of Galatia that they must give rigorous attention to doctrinal clarity, and that they also must remain faithful to the true Gospel he taught them, if they are to have any hope of being able to avoid losing their faith, in such a time as this, or have any hope of being able to avoid permanently falling away from their faith (becoming apostates). This advice, thus, is useful for modern-day believers, as well!
Without a doubt, people hurting from painful past memories need inner healing, and this inner healing is a God-given miracle. However, God heals when He wants, the way He wants, and at the speed He wants. So, if someone isn’t healed instantaneously or according to some believers’ timetables, then Christian wanna be advisers should take their lack of healing issue up with God and stop trying to dictate to hurting people when, in what manner, and how quickly they should get healed—and stop trying to blame hurting people’s hurts and pain on their lack of faith, and so forth!
