What does the Bible say about renewing our spirit?

The psalmist in Psalm 119:25 expresses a deep longing for spiritual renewal, stating, 'My soul cleaveth unto the dust; quicken thou me according to thy word.' This encapsulates the Reformed understanding that spiritual life and renewal come solely from God’s Word and His Spirit. In Romans 8:11, we see that the Spirit of Him who raised Jesus from the dead will also quicken our mortal bodies. Thus, spiritual renewal is not a product of our efforts but a divine gift that transforms our hearts and minds, enabling us to walk according to His will.
