Something tells me to keep knocking at heaven's door. If we still have unsaved love ones and friends then we should never never give up. As long as we are alive on earth our mission is not over.
If sin still have stronghold in our body or still antagonize us, there is still major battle to fight. But the battle will be fought for us by our Lord Jesus but He looks at our heart if we really mean business.
This is all for now.
I believe the improvement are these:
The battle has already been won by our Lord Jesus Christ but we have to claim our victory. Also when we keep knocking at heaven's door we will find out it is open and that we are to approach boldly to/into the throne of grace.
