How do we know we are in the family of God?

To know if we are in the family of God, we must examine whether we meet the criteria set by Christ Himself: doing the will of God, which is to believe on Him (John 6:29). The New Testament clearly outlines that true faith in Christ leads to an inner transformation, demonstrated by love for God and love for our fellow believers. 1 John 3:23 states, 'This is His commandment: that we should believe on the name of His Son Jesus Christ, and love one another, as He gave us commandment.' Thus, evidence of our inclusion in God’s family is marked by both faith in Christ and a genuine love for other believers.

Moreover, the assurance of being part of God's family can come through the working of the Holy Spirit within us. As Galatians 4:6 explains, God sends His Spirit into our hearts, affirming our adoption and providing a deep conviction and desire to live in a way that honors Him. This means loving our spiritual family and fulfilling the responsibilities we have toward one another, as empowered by God's grace.
