The Bible has strong words on foolishness, and some of those words are at odds with each other.
Do not answer a fool according to his folly,
or you yourself will be just like him.
Answer a fool according to his folly,
or he will be wise in his own eyes. (Proverbs 26:4-5.)
Other times, the role of being a fool yourself is called for.
If we are “out of our mind,” as some say, it is for God; if we are in our right mind, it is for you. (2 Corinthians 5:13.)
We can’t help but appear as stumbling fools to those who are steeped in thought systems and world views contrary to what Jesus said he was all about.
Jews demand signs and Greeks look for wisdom, but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles, but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God. (1 Corinthians 1:22-23.)
So don’t be afraid of appearing like a fool. If you belong to Jesus, lots of people are going to think that anyway. And as long as your life exhibits the fruit of the Holy Spirit, then whatever you do is fine no matter how foolish it might feel along the way.
Do you have something in mind you’ve wanted to try? Go ahead and try it. You’d be a fool not to.
