The apostle Peter writes to hurting and persecuted Christian believers, who have been “scattered” from their homes and familiar surroundings, and tells them to cast all their anxieties on God knowing that God cares for them (1 Peter 5:7). This is not some puff piece, or academic lecture, or thoughtless encouragement. Peter is communicating to real people, in real pain, and giving them real comfort. God cares about you!
“Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me; your rod and your staff, they comfort me“ (Psalm 23:4). We too often talk about God, without talking to God. We can give mental assent to certain Bible teaching – Jesus is Lord, Jesus is a Shepherd, Jesus is awesome – but not say to Jesus, “Rule my life as my Lord, be my Shepherd, help me to walk in awe of you!”
