What does the Bible say about understanding truth gradually?

In the New Testament, particularly in the book of John and Acts, we see that even the apostles did not have a complete understanding of Jesus’ teachings immediately. For instance, in John 16:12-15, Jesus tells His disciples that they cannot bear all the truth at once, but the Spirit will guide them into all truth gradually. This indicates that understanding unfolds over time, aligning with God's patient and merciful character. The example of the apostles’ confusion about the kingdom of God (Acts 1:6) and Peter's struggle to understand the inclusion of Gentiles (Acts 10) illustrates that God doesn't expect His children to grasp everything at once but teaches them progressively.
