Of Moment Frames and Church Hymns

One song that we sometimes sing at my church has a verse from an old hymn mixed into it:  “I dare not trust the sweetest frame, but wholly lean on Jesus’ name”.

In my profession, we use different types of frames to resist earthquakes and wind forces.  In our area, two types dominate: moment frames and concentrically braced frames. Over the years, I’ve gotten to attend seminars and read trade journal articles about other types of frames like eccentrically braced frames, buckling-restrained braced frames, and special truss moment frames that attempt to withstand wind and earthquake forces in their own way, and with varying levels of efficiency. But always, I am reminded that even with the best plans, the latest tools, the newest techniques, the most up-to-date research, the most complex analyses, and the most complete calculations, they are all still fallible and not completely trustworthy, just like the “sweetest frames” that were rendered into rubble during the Northridge earthquake of 1994.

Despite our best attempts to make trustworthy frames of our own to withstand life’s unexpected disasters, there is only one sure foundation, only one support who can take our heavy burdens without yielding, only One who is worthy of all our trust, no matter what. That the fallible designs of our minds and the imperfect works of our clumsy hands are not the best there is; that we don’t have to resign ourselves to only being able to trust in things or people that have disappointed us before and likely will again; that rather we can “wholly lean on Jesus’ name” as the one stable and unmovable framework in our lives; that’s something to be grateful for!
