How do we know our adoption as God's children is true?

The assurance of our adoption as God's children does not come from our feelings or the opinions of others, which can be misleading. Instead, it is the Holy Spirit who bears witness with our spirit that we are indeed children of God (Romans 8:16). This internal testimony is crucial, especially when doubts arise due to our sins or the hardships we face in life, which might falsely challenge our assurance of sonship. Even in our weakness and struggles, the Spirit's witness provides a firm foundation for our confidence in God's love and the reality of our adoption. Thus, we can affirm that our status as God's children is secure, regardless of external circumstances.
