V.1-2 If you have quiet confidence in the Lord, even if you have difficulties in your life, you are going to be thinking like these two verses. Do you believe that? Do you see that third word in the first verse? The Lord would be happy to show you what He is waiting to do for you if you ... Him!
V.4 We sometimes say to our children “Be good now.” Do you want the Lord to “do good” to you? What does the Lord expect us to be? Upright in heart. Do we need to ask Him to help us to be this? (Read 2 Peter 1:3-4).
V.5 This will be the end of those who turn to do their own will. But the Lord doesn’t want to end the Psalm like that. The Psalm starts with “trust” and ends with “peace.”
