"Oh, what joy for those whose disobedience is forgiven, whose sins are put out of sight. Yes, what joy for those whose record the Lord has cleared of sin." - Romans 4:7-8
Jesus came and washed our slate clean, but do we show a gratitude and a grateful heart? Jesus has forgiven our sins through His blood, if we are his disciples we need to find forgiveness in our hearts for those have wronged us. Do not hug your grudge or it will grow and it will cost you.
