That disobedience in our heart makes us cold toward others. The second condition that blocks the flow of warm fuzzies is a hard heart and proud mind. The hard heart is caused by our constant refusal to accept the other person and be kind to them. Every time we see them and we refuse to give acceptance our heart calcifies a little more. That calcification reduces our ability to love our spouse, children and others whom we like.
Pride is the catalyst that starts the hardening process in our hearts.
Its the desire to have our private pecking order. If we are serious about being disciples of Jesus, then we must confess to God the attitudes and actions that separate us from our brothers and sisters. Remember, the problem is not psychological but spiritual. Jesus said that His followers are known for their sacrificial love. Jesus said that without that love we cannot be His disciple.
