¹⁰ All who believe in the Son of God know in their hearts that this testimony is true. Those who don’t believe this are actually calling God a liar because they don’t believe what God has testified about his Son.

¹⁶ For his Spirit joins with our spirit to affirm that we are God’s children.

⁶ And because we^[a] are his children, God has sent the Spirit of his Son into our hearts, prompting us to call out, “Abba, Father.”^[b]

³³ Anyone who accepts his testimony can affirm that God is true.

³⁸ and you do not have his message in your hearts, because you do not believe me—the one he sent to you.

Faith in the Son of God

5 Everyone who believes that Jesus is the Christ^[a] has become a child of God. And everyone who loves the Father loves his children, too.

¹⁰ If we claim we have not sinned, we are calling God a liar and showing that his word has no place in our hearts.

¹² Be careful then, dear brothers and sisters.^[a] Make sure that your own hearts are not evil and unbelieving, turning you away from the living God.
