1:6

Here Paul mentions that the Corinthians believed Paul's message about Jesus. His testimony or witness was confirmed, or established, in them.

In the parable of the sower, Jesus taught that the kingdom of God was like a plant. The word of God is like a seed, and the listeners are like soil. Those listeners who "hear the word and understand it" are like good soil, which receives the seed and helps it to grow. When a seed gets down into good soil, it sprouts and roots. As it grows, it gets taller above the soil, and gets stronger in its roots below the soil. We all know how strong trees can get, and how hard it is to uproot them when they are large.

In the same way, Paul's message (the seed) took root and grew in the Corinthians' hearts. They accepted his words about Jesus and believed.

That's why hearing God's Word through the Bible and through godly preaching is so essential - it helps us to grow and become more rooted in Him. If you don't have a regular time of reading and studying the Bible, I encourage you to make that time. You won't be sorry.
