Comfort to me is knowing that my transgressions are forgiven, my sin is covered and the Lord does not impute iniquity to me. I am not on course to hell without my creator, this is a great comfort.

Forgiveness can only be accomplished because of Christ's sacrifice on the cross. Knowing the pain and the cost which my sin caused Christ urges me to try and live a life worthy of His calling, only possible by the indwelling of the Holy Spirit.

That I, a mere worm have been called with a Holy calling. My body is not my own but God's temple where the Holy Spirit resides. Sin should not be taken lightly for I was bought at a price.

For me knowing where the Spirit of the Lord is (within me) brings me great comfort. What freedom I have been given. For nothing shall separate me from the love or presence of God.
Whatever is before me I have no need to fear or to be anxious because all things work together for my good because I love God and have been called according to His purpose.
