Despite being mentioned frequently in the same breath as his adventurous father Abraham and son Jacob, Isaac never really does much in the Bible. In the few chapters devoted to Isaac, things happen around him and to him, but he rarely makes much of an effort to cause anything to happen.
Isaac certainly had his share of shocks and traumas when he was young: being blamed for losing his brother, almost being killed by his father then being mysteriously spared, and being surrounded by mocking laughter in his youngest years when seen with his aged mother. Imprisoned by memory and his fear of doing more things wrong, he sits and lets events play out as they will.
Do you find yourself doing things based not on what is happening now but in reaction to similar things that happened long ago? How might things be different if you focused just on what was actually happening now? Are these habits and reactions a problem, or have you benefited from the ways that you have learned to behave and react?
