There are simply times when we can't find words adequate to express any more clearly how deeply we are moved than0 to say our heart is broken.
And for those times that this is tied to crushing loss it can be a while before that loss and the blessings that made the loss so acute get woven into our lives so we can move forward.
But I feel that anytime we describe the depth of emotion as being heart breaking it is because embedded in the experience is the capacity to have it change us in profound ways. Certainly as we grieve a loss we reach a time where we move forward from a new place, comforted to know that a parent's love helped equip us to handle their passing or the death of a dream of expectation was necessary to make room for a new opportunity. Seeing a moment of nature's beauty or power can open us to considering how it all happened to be. The emotions surrounding the birth of a child are necessary to bestir us to do the best by that child that we can.
Is your heart breaking? Are your emotions floating to the surface in ways that leave you feeling vulnerable? Do you feel your life is changing faster than you can keep up? Know that God is not "out there" but rather wrapping you in His love. All you are experiencing is not going to be wasted because God has a plan to bring you through this in a way that draws you closer to Him. The sense of things changing is valid at any time because noting stays the same through the course of our years except this one important thing: God loves you, longs to offer you comfort, discernment, and hope.
Won't you speak to God of your deepest feelings, fears and longings? God cannot love you more and will never love you less than God does right now and His greatest wish for you is your highest good.
