The Bible say that one should check himself weather He/She is standing or not. That is weather you are for God or you are for satan.

before being forgiving, one is incomplete, sad, bitter, sick in d inside but when u are speak out in confession, joy flows. i remember when i had an unfair relationship, i was sad, bitter, i find it difficult to go on my kneels but when i surmmon d courage to seek GOD'S face with humility he forgive me and i recovered my joy.

 so therefore,being forgiving make u feel GOD is merciful and this will increase d love for GOD in our lives.
