A “Catalyst” is defined as a substance, usually used in small amounts relative to the reactants, that modifies and increases the rate of a reaction without being consumed in the process. Note 3 important parts of the definition - small amounts, increases rate of reaction (or change), and not consumed in the process.

Jesus is the ultimate catalyst. He doesn’t overpower you, even though He could. He says that He uses a “still small voice” to get your attention. And, He speeds up change and never is changed. How can you be more like Jesus when you decide to have a difficult conversation with someone? 

Here is God’s "catalytic" approach. Galatians 6:1-5 (NKJV) – "Brethren, if a man is overtaken in any trespass, you who are spiritual restore such a one in a spirit of gentleness, considering yourself lest you also be tempted. Bear one another’s burdens, and so fulfill the law of Christ. For if anyone thinks himself to be something, when he is nothing, he deceives himself. But let each one examine his own work, and then he will have rejoicing in himself alone, and not in another. For each one shall bear his own load."
