Nothing that causes you to avoid or to mistreat another human being is worth holding on to. Search yourself and if you just can’t seem to let that thing go, be honest with yourself, are you using it as an excuse to act badly towards someone or are you seeking attention or sympathy from others. Remember that God knows all and He sees everything,. We will be judged by our actions and we will give in account for our wrong, period! God gave His only Son for the forgiveness of your and my sins so why do we have the right to hold on to anything against anyone?
Now, as we all prepare to be with family and friends, pray and ask God to help you to be kind and show love. He looks over our faults everyday and still gives usgrace and mercy. Try doing the same.
