In this passage, we see some people that were similar to Apollos, but different. Like Apollos, they had been disciples of John, but unlike Apollos, they were unaware of the one John had been pointing to.
So while they had been baptized by John, they had probably left him before Jesus’ baptism, and John’s declaration of him. In other words, they had repented of their sins, but were not yet following Jesus.
And so Paul taught them about Jesus, after which they believed and were baptized both in water and in the Holy Spirit.
I suppose that if there’s one thing to get from this passage, it’s that it’s not enough to be sorry for your sins and repent. It’s not enough to say that you want to follow God. You also must put your faith in Jesus. Jesus isn’t one of many ways to God. He is the only way. And if you don’t have him, you have nothing.
How about you? Have you put your faith in Jesus? It starts with a prayer.
Father, I know that I have sinned. I’ve been going my own way and have hurt you, others, and even myself. Forgive me. I believe that Jesus died on the cross for my sin and rose again. Now be my Lord. Be my king. From now on, I want to follow you. In Jesus name, amen.
