According to 1 John 5, we can know we are children of God by our faith in Christ and the evidence of His work in our lives.
1 John 5 provides clear indicators of being a child of God. The primary evidence is faith in Jesus Christ as the Son of God, which leads to being born of Him. Additionally, those born of God display a love for others and a desire for holiness. The transformation seen in their lives—an aversion to sin and a pursuit of righteousness—shows that they are truly part of God's family. John confirms that this knowledge is rooted in the truths of the Gospel and the internal witness of the Holy Spirit, providing believers with confidence in their identity as children of God.
