Apart from such external things,
there is the daily pressure on me
of concern for all the churches.
Who is weak without my being weak?
Who is led into sin without my intense concern?
II Corinthians 11:28-29
Iron sharpens iron, so one man sharpens another.
For I long to see you so that I may impart
some spiritual gift to you, that you may be strengthened;
that is, that I may be encouraged together with you
while among you, each of us by the other's faith,
both yours and mine.
In the church we are all weakened by the weaknesses of others, and we are all strengthened by the strength of others.
