In Matthew 7:21, Jesus said, "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but the one who does the will of my Father in heaven." Does this mean that a basically good person may not make it to the kingdom of heaven? I see at least two instances in which this can happen. (1) You don't obey God in all things. For example, you find it difficult to forgive someone. Whereas you should go to God to seek help, you decide that you are just not going to forgive that person. This is deliberately going against the Lord. (2) You believe that you are a good enough person and that it's OK to commit some small sins now and then. This lack of humility can also keep you out of the kingdom of heaven. The bottom line, we need to do the will of our Father in heaven as best we can.
