What does it mean that Samuel grew in favor with God?

When the Bible states that 'Samuel grew,' it encompasses both physical growth and spiritual maturation. 1 Samuel 2:26 notes that Samuel 'grew on and was in favor both with the Lord and also with men.' This suggests that as Samuel matured, he not only gained wisdom but also experienced the blessings of God. Such growth is indicative of God's active involvement in the life of the believer. For every Christian, growth in grace and knowledge of Jesus Christ is a sign of being taught by the Lord, as stated in Isaiah 2:3. It reflects the ongoing nature of sanctification in the believer’s life.
