The Word of God made flesh taught us what this means: https://bible.knowing-jesus.com/topics/Jesus-Christ,-Holiness-Of
God has given us many doctrines in His Word that we are to study and meditate on. Timothy was a shepherd of God’s flock, and his meditations on the Word were to the great profit of many who heard him. We cannot tell how God will use our mediations on and devotion to His truths or how many people may be blessed by them.
And we pray:
O Lord, help me to find a quiet time to meditate on Your Word. And let it also be my meditation all the day. Help my thoughts to turn to You in the little pauses and intermediate moments of this day. I know You can change me through Spirit-led meditations on Your Word and that You can bless others as a result as well. Amen.
