"Romans 5:2-6"

In the middle of distress? In the middle of sorrow? In the midst of sin & guilt? (That sorta sounds like one of those Commercials for a Personal Injury Lawyer) But if your answer to any of those questions is yes, that means that your journey isn't over, and the power to rejoice in the midst of this life comes from the hope of God's glory.
Through Christ we have the ability to access the power of grace through faith, and through that power we have obtained the freedom to stand in the midst of this world. We have secured the ability to rejoice in midst of any problem. Not that we will have an answer for why God allowed it to happen, or that mourning will not take place (Mourning is an essential part of properly rejoicing God in the midst of sorrow.), but rather that a beautiful worship will take place in the midst of pain.

When we rejoice in our sufferings and look forward to the perfect joy that is to come, a certain endurance is built up in our spirit. Similar to the way that constant use will make our hands callous, constant acknowledgment of the sorrow produced by a sinful world will build a thick endurance that creates that Christ like character we all strive for. That character in an almost indistinguishable way will cause us to always look forward to the hope of heaven, to the realization that if it isn't perfect, it isn't over.

That hope in heaven, that hope in grace, that hope in God's sovereignty will not disappoint or let us down, but will rather be built inside us by God's love that has been poured into our hearts by the holy spirit. His companionship and love will provoke us to worship in the midst of our hardest times.

But in the end, just remember, that if it isn't perfect, it isn't over.
