Design Life

My husband was an engineer when we were first married & he schooled me on the idea of design life – everything is created with a design life (length of time for which it will be functional). This was a new idea to me when he explained it & now, I’m not as surprised when things stop working. For example, our phones have a design life of about 2years & the phone charger in my car seems to have a design life of maybe 3months :/
Thankfully, the design life of our relationship with God is eternal & infinite, a sharp contrast with everything human 🙂
