How do we know God's favor is true?

The scripture states that 'Good understanding gives favor' (Proverbs 13:15). This favor, or grace, is associated with wisdom, which is ultimately found in Christ. When believers possess this understanding, they reflect God's love and favor upon them, being recognized as sons and daughters of God. This not only affirms their relationship with Him but also highlights that they are favored not due to their own merit, but because of the righteousness of Christ they possess as a gift. Thus, God's favor is manifested through His gracious choice and the wisdom He imparts to His elect.
