Discovering the depths of God's knowledge requires recognizing how little we truly understand about Him. Paul's prayer for the Ephesians (Ephesians 1:15-19) teaches us four essential principles: prayer rooted in Christ begins with a thankful heart, asks for wisdom and knowledge, is full of hope, and seeks God's power to accomplish His mission. We must approach God with humility, recognizing that all true knowledge comes through Jesus and Scripture, illuminated by the Holy Spirit. When we lean into what God has called us to do with thankfulness, wisdom, hope, and divine power, we can participate in changing the world.
