I have A LOT of firsthand experience with the consequences of suppressing feelings.  For many years I avoided my pain and my feelings because they felt so intense and scary (now I understand that is partly because I'm highly sensitive and that makes feelings a bit more magnified). Anyhow, when the Lord started taking me through deliverance and inner healing about 7 years ago, He had me facing all those suppressed feelings and asked me to feel and address them once and for all. It was really scary and confusing still for a while because it often felt like regressing into the effects of long years of trauma... but...God proved Himself faithful and over time the waves of sadness, grief, fear and anger began to die down as He guided me through feeling it all. It is so much more wise to let ourselves feel and be present when life happens. I've been learning to do that as God has carried me along with His amazing loving Presence.  

And...He will give us the discernment we need to figure out if what we are feeling is from Him and a path to walk down or if it is something self-indulgent or a counterfeit of the enemy.  Many Christians teach that feeling feelings is a bad thing as if we have to live life perpetually pushing beyond our feelings in the idea that we must "pick up our crosses and deny ourselves"...but this can be a very dangerous idea and a Scripture, along with many others, that is often taken out of context.  There are times when the enemy will tempt us to self-pity or into a manner of feeling that is UNHEALTHY, however, this is to be carefully decided by the wise and mature who understand how to discern the source of their feelings.  The wise don't go to extremes with all this as there are many feelings that, if we do not face, will come back later with a vengeance until we acknowledge and walk through them. Our feelings are not inherently evil nor are they mostly our enemies. They are most often gifts that God uses to mold and shape us into who He's called us to be and a necessary part of our human journey in a broken world. Thank You Lord for feeling in healthy ways.
