Please pray

The Archbishops of Canterbury and York have also issued a special prayer

God of peace and justice, 

We pray for the people of Ukraine today. 

We pray for peace and the laying down of weapons. 

We pray for all those who fear for tomorrow,

that your Spirit of comfort would draw near to them. 

We pray for those with power over war or peace, 

for wisdom, discernment and compassion

to guide their decisions. 

Above all, we pray for all your precious children, at risk and in fear, 

that you would hold and protect them. 

We pray in the name of Jesus, the Prince of Peace. 

Amen.
