How do we know we are God's children?

The assurance of one's status as a child of God comes through the work of the Holy Spirit in the believer's heart. Romans 8:16 tells us, 'The Spirit himself bears witness with our spirit that we are children of God.' This affirmation gives believers confidence in their identity and relationship with God. The heart's cry of 'Abba, Father' signifies an intimate relationship with the Father, urging believers to seek this realization earnestly, as it reinforces their assurance of salvation and belonging.
