Author Henri Nouwen, in his book The Return Of The Prodigal Son, suggests that all Christians, at some point in their walk of faith, are represented by each of the three main characters. At times we are the wayward child in need of repentance and forgiveness. At other times we are the big brother who wants to hold on to resentment and withhold forgiveness. But as we mature, we become like the father, whose highest desire is to have all his children reconciled.
The church is also a big family, we should not be split into separate parts as 1 Corinthians 1:10 records "I appeal to you, brothers and sisters, in the name of our Lord Jesus Christ, that all of you agree with one another in what you say and that there be no divisions among you, but that you be perfectly united in mind and thought."
1 Corinthians 12:12 Just as a body, though one, has many parts, but all its many parts form one body, so it is with Christ.
Paul encouraged the Corinthians in their trials: "Do not look at the things which are seen, but at the things which are not seen. For the things which are seen are temporary, but the things which are not seen are eternal." (2 Corinthians 4:18)
So what's unseen and eternal that we can focus on? The character of God is an excellence place to focus. He is good (Psalm 25:8), He is just (Isaiah 30:18), He is forgiving (1 John 1:9), and He is faithful (Deuteronomy 7:9).
A right attitude with your family begins with a right attitude toward God.
