We stand firm in the Lord by realizing that God is in control and He will take care of us. Our confidence needs to be in the Lord alone. While we are living this life, we need to cast off anything that does not follow God's plan. The Bible does not say, do not feel anxious, it says, do not be anxious. Likewise, the Bible does not say, do not feel fear, it says, do not be afraid. We can always find a reason to rejoice. If people imitate us, what will they be doing? We need to imitate the good things that we see others doing.
God has given us all a ministry, a mission, something that God wants us to do. We need to stay focused and accomplish our tasks.
