How do we know the doctrine of a fixed heart is true?

The doctrine of a fixed heart finds its truth in Scripture, particularly through passages that emphasize the work of the Holy Spirit in solidifying a believer's affections towards God. Psalm 57:7, where David proclaims, "My heart is fixed, O God, my heart is fixed; I will sing and give praise," illustrates that true worship arises from a heart aligned with God's purpose and presence. This alignment is not achieved through human effort but by the grace of God through the Holy Spirit, who enlightens the heart and draws it into intimate relationship with Christ.

Furthermore, this doctrine is confirmed through experience. Believers who seek the Lord earnestly often testify to finding joy and satisfaction in God when their hearts are resolutely focused on Him. The consistency of this message throughout the Scriptures, coupled with personal spiritual experiences, serves as a strong affirmation of the truth behind cultivating a fixed heart.
