We all process life differently, like solving a math problem in our heads. Some of us break numbers down, others visualize patterns, and still others reach for a calculator. This simple truth reveals something profound about our spiritual lives: we each have patterns of thinking that shape how we relate to God and respond to His call. In Matthew 21, Jesus tells a parable about two sons that challenges us to examine not just what we say, but what we actually do. One son boldly refuses his father's request to work in the vineyard, yet later changes his mind and obeys. The other son eagerly agrees but never follows through. The question Jesus poses cuts to the heart: which son did the father's will? This isn't just about ancient tax collectors and prostitutes entering the kingdom ahead of religious leaders. It's about us, right now, in our messy inconsistency. We flip-flop, we say yes when we mean no, we promise God things we never deliver. But here's the beautiful truth: we can change our minds. That phrase, “changed his mind,” is the same word as “repent” in the original text. Whether we've been living in open defiance or quiet disobedience, whether we've been saying the right things while our hearts remain far from God, we have this moment to turn. The call is to do the hard things, to sacrifice what we hold dear, and to submit our hearts fully to the Father. It's not too late to become the obedient child, to move from rebellion to faithfulness, from words to action.
