1 Peter 1:2 …have been chosen according to the foreknowledge of God the Father…
You who are obedient to Jesus Christ and his command to love, have been chosen by God. You have been chosen to be children of the Father, brothers and sisters to Christ.
You are now chosen for eternal life. you are chosen to be full of the spirit and guided by the Spirit of Christ. This is not presumption this is a fact. You are a child of God now obedient to the command to love.
Absorb this fact. Let this seep into your heart. Aknowledge this in your mind and in prayer to the Father. Thank him that he has chosen you for eternal life and Sonship. Take time to let this really enter into you and let this knowledge guide you and fill you as you walk to carry out his will daily.
