The second requirement before a sheep will lie down is to be free from friction. (Not at odds with others).
Because of their social behavior sheep will refuse to lie down unless they are free from friction from those within the flock. Sheep have a social or butting order just as other animals. Many times we as Christians find ourselves butting heads with other Christians.
Christians in the New Testament had to deal with this problem of division and friction just as we deal with it in our lives today. Having this to spill into our churches will kill a church's growth as well as kill our Christian witness.
Paul addresses this issue in several of his epistles. In the first letter to the Corinthians he laid it out pretty plain (I Corinthians 1:10-17).
At one point he says he thanks God he didn't baptize any of them.
I Corinthians chapter 12: Paul teaches that we should work together putting aside our differences and envies. We are to use the special gifts God has given us to grow the flock.
Ephesians 4:1-16: God's word tells us that we should be united because through unity the body will grow and mature.
Verses 20-32 tells us to be kind and treat each other with love and forgiveness as Christ forgave us.
Let us be as the Christians in Acts 4:32 let us be in one accord having all things in common, so we can lie down in green pastures.
Paul blesses in Romans 15:5-6 that God grant us to be like-minded toward each other that we may glorify God.
Christians are like snowflakes, frail but if they stick together they can stop traffic.
Pray for unity.
