If the LORD delights in a man's way,
he makes his steps firm;
Firm steps. That’s what we all want, to walk without slipping, to progress without faltering. God will do this for us if He delights in our way. If he is pleased by how we live. This is another one that seems to just make sense. Sometimes it is my “stumbling” or “falling” that teach me the most. When I am travelling in a way unpleasing to God I should rejoice that my steps are not firm, that I will likely slip and fall at any time rather than continuing on in the way of destruction.
I’m reminded of the Tower of Babel when God said, we’ve got to stop them; if they’ve come this far imagine what they might do next. Only when our ways please the Lord will our actions serve to truly build up ourselves and humanity, and only in those ways do we deserve to walk with a firm step.
