Hearts can be softened and transformed by the Holy Spirit.

I will give them a new heart and a new mind. I will take away their stubborn heart of stone and will give them an obedient heart. ²⁰ Then they will keep my laws and faithfully obey all my commands. They will be my people, and I will be their God. – Ezekiel 11:19-20 GNT

I pray for my heart to be softened and transformed. I pray and repent from my own anger, hatred and bitterness. May I have compassion on others as Jesus did and forgive others.

I pray for a heart that is fully devoted to God and is filled with the presence of the Holy Spirit so that He can lead.
