What I have personally learned about my experiences with being triggered is that sometimes God will allow that triggering to happen within us to get our attention of what needs to be dealt with within us.
Not only that, but God will also lead us into a situation or relationship similar to what we have experienced in the past that has caused us harm so that we can have an opportunity to retrain our brains that what it fears is no longer a threat. This is known as exposure therapy.
I am sharing my own recent experience with being triggered and exposure therapy to help you learn to have ears for the Lord’s voice if you find yourself in similar circumstances. God wants you healed and whole, but it takes some work on our part to see that happen. Mostly, it takes us being in a place of humility to accept what is happening within us so we can then invite the Lord to bring us healing.
