Oftentimes as we grow in our relationship with the Lord, He enables us to begin taking our attention off of ourselves – where we so naturally focus – and to become much more interested in those around us.
You might compare it to a photographer who always likes to use his zoom lens. There are many marvelous, exciting, beautiful things to behold all around him, but he is so focused on that one thing, he misses all the rest! Frequently, our “lens” is set on the zoom mode; so focused on my life, my family, my church, etc. But over time, God begins to widen the lens in our life and our heart - to see and behold all the other marvelous ways in which He desires to use us. There’s suddenly a panoramic view!
God desires for all of us to 'widen our lens', to step outside our comfort zone, to reach out beyond our safe, comfortable church groups, for the sake of His Name and His glory.
Fellowship with our brothers and sisters is indeed wonderful and powerful and beneficial for building up the Body of Christ. Proverbs 27:17 says: As iron sharpens iron, so a friend sharpens a friend. But let's not stop there. Jesus said to his followers: The harvest is great, but the workers are few. So pray to the Lord who is in charge of the harvest; ask him to send more workers into his fields.
There's a great big field to focus on right outside our church doors!
