What does Mark 4:24 mean?
It's crucial to take Mark 4:24–25 within the context of the whole chapter. Jesus is speaking about different reactions people have upon hearing His teaching. Mark 4:1–20 describes people who have hardened hearts, shallow personalities, greed, or faith in Jesus and a willingness to listen. Mark 4:21–34 gives further detail about the spread of the gospel.The "more" that will be added isn't power, influence, or material possessions. It's spiritual wisdom. Jesus is saying that if we approach His teaching as if we were carrying a big basket, our basket will be filled with understanding and enlightenment. Jesus' disciples embody this when they stay to learn when the miracles are over (Mark 3:33–35) and ask for insight into the parables (Mark 4:10).
We have a lot of choice and control over our Christian life. Matthew 7:1–5 explains that how we judge others' actions will influence how they judge ours. Luke 6:37–38 adds that our personal policies on forgiveness and giving will determine how others forgive and give to us. It's the same with spiritual knowledge. Knowledge of the kingdom of God increases and decreases exponentially. If we bring a large vessel to be filled with knowledge, it will be filled to overflowing. If we bring a small one, it will be filled initially, but then lost (Mark 4:25).
Our "measure" consists of our time, attention, and submission to Jesus' words. Personal devotions, regular church attendance, and intentional application of Scripture in our lives are parts of a large measure. The more we ask for, the more the Holy Spirit will work in our lives, above and beyond the details of what we have learned. It is our choice to ask for wisdom (Matthew 7:7–11; Luke 11:9–13) and it is our choice to decide how much wisdom we will ask for (Mark 4:33). God will honor our request (James 1:5).
