We know we are adopted into God's family because the Spirit testifies to our spirits that we are children of God (Romans 8:16).
The assurance of our adoption into God’s family comes from the internal witness of the Holy Spirit as outlined in Romans 8:16, which states that the Spirit bears witness with our spirit that we are the children of God. This means that every believer experiences a profound inner confirmation that they are indeed part of God’s family. It is important to note that this assurance is not dependent on our feelings or actions; rather, it rests on the promises of God’s Word, as we trust that God saves sinners and calls them His own. Our status as adopted children is a sovereign act of grace that reveals our identity in Christ.
