Why is it important for Christians to know they are adopted as sons?

Understanding our adoption as sons of God, as mentioned in Galatians 4:5-6, is crucial for Christians because it affirms our new identity and relationship with God. This privilege of being called ‘sons’ signifies that we are no longer under the law but are heirs of God through Christ. God has placed His Spirit in our hearts, enabling us to cry out 'Abba, Father,' demonstrating intimacy with our Creator. This adoption grants us the assurance of our salvation, reinforcing that it is not contingent upon our performance but grounded in God's promise and grace. Thus, it cultivates a sense of security, encouraging believers to approach God with confidence and trust in His love and commitment.
