Is this not the Son of Mary, and the brother of James, Joses, Judas, and Simon? And are not His sisters here with us?" So they were offended at Him."
Mark 6:2-3 (NKJV)
Sometimes when we accomplish something, or if we do something that people did not expect us to be able to do, people might be impressed by what we did, but it can also be that people will criticize us. If this happens, then we have a choice, will we listen to those people who praise or criticize us, or will we continue to do what we are doing? If we are doing what is right, then we should not allow the praise or criticism from anyone to stop us from doing what we need to do.
Although Jesus is the Son of God, and He did the will of God, not everyone was happy with Jesus and pleased with what He did. In Mark 6, when people heard Jesus teach in the synagogue, they wondered how He could teach the way He did, and people were offended by Jesus and His teaching. People talked about the natural background of Jesus in a way that seemed to say, "We know His family, we know Him, who does He think He is?", but this did not matter to Jesus, He just kept doing the will of God.
Jesus knew Who He was, He knew the will of God for His life, so Jesus did not allow the criticism, or the praise of people to change what He was doing. Jesus never changed His teaching to please His critics; Jesus taught the truth from Scripture, even when people did not like it. We need to be the same way, and know who we are in Christ, what God has called us to do, and follow the direction of the Holy Spirit. Then we need to keep doing what God has said, no matter what others say about it; we need to know Who we should listen to.
