Earlier in the gospel of Mark, the disciples had cast out demons, but they failed to do so in chapter 9 as we read earlier this week. We do not automatically get all that we desire in life. We must therefore learn to discern what is necessary for us to do God’s will. That should be our priority. Trusting and having faith in Him starts with Him (Ephesians 2:8-9) and grows as we make it a daily practice. In verse 29 Jesus says that prayer is crucial, so we must also learn to pray.
