The divine favor is His grace. God desires to fill you, little children, with His grace. Without the grace of My Son your works would be fruitless. Grace strengthens your faith, which is your salvation. Salvation does not stem from your own works but through the immeasurable riches of His grace.
Grace gives joy.
It is also the main source of your courage. You are who you are through the grace of God. My Son is faithful in bestowing His grace. He is merciful and gracious. He is abounding in steadfast love.
