How do we know we are part of God's family?

Membership in God's family can be identified through three significant aspects: being born into it, adopted into it, or married into it. As believers, we acknowledge that we have been born anew in Christ, adopted as sons and daughters, and united with Him in covenant love. In Ephesians 2:4-5, it declares that God, rich in mercy, has made us alive with Christ even when we were dead in our sins. If we can consciously ascribe all authority, work, and love to Him, then we are indeed part of the brethren and thus part of God's family. This work is His alone, emphasizing His sovereignty in our salvation.
