Why is hungering and thirsting after righteousness essential for Christians?

Hungering and thirsting after righteousness, as described in Matthew 5:6, denotes a profound spiritual yearning for the holiness and purity that God requires. True believers recognize that they cannot attain this righteousness through their efforts, which are deemed as 'filthy rags' (Isaiah 64:6). Instead, they seek the righteousness that comes from God alone, found through faith in Jesus Christ, who is called 'the Lord our righteousness' (Jeremiah 23:6). This hunger reflects an ongoing sanctification process, where believers continually desire to live in accordance with God's will, and they are promised satisfaction as they find their righteousness in Christ.
