Self-sufficiency is something that is ingrained into our Western culture. It is a myth, quite demonstrably so. We cannot build a house, nor a life without the tools and experiences we have received from others. Self-sufficiency leads to self-dependance where we do not think that we need other people at all. We think we don’t need God either, though we do. Stop and think about how other people have contributed to your life. Stop and think of how you need the sustaining grace of God every moment.
“Come now, you who say, ‘Today or tomorrow we will go to such and such a city, and spend a year there and engage in business and make a profit.’ Yet you do not know what your life will be like tomorrow. You are just a vapor that appears for a little while and then vanishes away. Instead, you ought to say, ‘If the Lord wills, we will live and also do this or that.’ But as it is, you boast in your arrogance; all such boasting is evil.” James 4:13-16 (NASB)
