As strong Christians, we're expected to be leaders to those who aren't. However, the idea of supporting the weak in a way that leaves them still weak is of no benefit—we are supposed to be building them up. Romans 15:1-3 says in part, "Now we who are strong ought to bear the failings of the weak...to build them up."
Imagine a person who is too weak to pick up a box. We can do everything for them, and the task gets done, but the person builds no muscle and remains weak, or we can help them enough that they work and grow muscle, until they can do it on their own.
It's tempting to only help a little. Maybe someone has a personal life that's a train-wreck, but polishes up well for assembly, so we think, "Eh, have 'em lead a prayer or a devotional and that'll be enough." Strength training is not an hour-a-week thing. Ultimately we leave that person the same as before: still weak. Let's take the time to focus on the PERSON, which means their—and our—PERSONAL lives. It's not the easiest path and it has no shortcuts, but it's the one that leads to gains.
"For the entire Law is fulfilled in in this one word: "You shall love your neighbor as yourself."—Gal 5:14
