Sometimes we forget what Christ has done for us. Our forgetfulness creeps into our daily attitudes; moods and treatment of others.
But when we remember what Christ has done for us, it can alter our approach to life. I remember one podcast where people sent in questions about life. A pastor prepared a response. This time the question revolved around anger and bitterness towards a family member. The questioner wondered how they could overcome the anger they felt towards this person. Every time they encountered them, resentment would well up inside and spill out.
