When we lose one of our own children, our baby that is within our womb, we naturally know that all is not right with the world. We cry out to God - why?!? Why would you allow this suffering? But, if we are truly believers in Christ, we know that the "what" that is not right with the world is called "sin". We know that back in the garden of Eden, sin was committed, and at that point in time, death entered the world because of sin. And deep down we know that it is not only Adam and Eve who sin, it is we who sin as well.
This is what causes us as believers to mourn. We not only mourn our babies in death, but we mourn the sin that brought death into the world. We hurt because we know that all is not right with the world. This death was not part of the original plan of God. We long for a day when sin will hold no power, and death will lose it's sting.
This is right where God wants us. Jesus himself tells us that those who mourn are blessed and they shall be comforted. Was He only talking about mourning tragedy? No, He was speaking of mourning over sin. When we mourn over sin, we will be comforted. It's a promise. Mourning over sin encompasses the idea of turning away from sin and placing faith in Jesus Christ. This lets me know that the only way that I can truly be comforted in my time of loss is by mourning over sin (my sin in particular) and mourning over the death that sin brought.
I am not concluding in any way that a particular sin in my life or yours is what brought about the miscarriage. I am simply connecting the dots between sin and death. They, in fact, cannot be disconnected. But think with me for a moment . . . when we truly mourn over our sin, we are comforted by the forgiveness that is brought about by Jesus' death on the cross and resurrection from the dead. If we want to be fully comforted in our grief and suffering, this is the only way. Through Jesus' sacrifice, we now have a way to enter into the place where Jesus will wipe every tear from our eye. We now have a way to be completely delivered from death unto life. We have a way that we can be completely and forever healed.
Our babies have escaped the pain of sin and death in this world and are with the Father, complete and whole. But the true question is, will you mourn, not just for the loss of your baby, but over your sin, so that you will be forever forgiven and in that way, completely comforted?
Our miscarriages are an opportunity - an opportunity to fully turn to Christ in true mourning, for He longs to comfort you by forgiving you, and giving you an opportunity to become a part of those who populate His paradise, right alongside your baby. If you've already come to Him in repentance and faith, truly mourning over sin, we can be comforted in the fact that the day is coming when death will not have the victory. All that is wrong with the world will be made right, for “blessed are those who mourn, for they shall be comforted.
