How do we know God's love for His children is eternal?

God's love for His children is an eternal and immutable love that does not waver. As described in John 3:16, His sacrificial love is demonstrated through the giving of His Son. The Apostle Paul reinforces this concept in the context of God's promises by stating that just as the Father loves the Son without condition, so He loves His children with an everlasting love. Romans 8:38-39 further assures us that nothing can separate us from the love of God, affirming its eternal and steadfast nature.
