Let your will be done on earth as it is in heaven.
What does this mean?
God carries out his good and merciful will all by himself without our prayers. However, we pray in this request that God would carry out his will through us as his willing servants.
How is that done?
God’s will is carried out when he neutralizes and blocks every evil plan or desire that would like to prevent us from making God’s name holy or letting his kingdom come, such as the will of the devil, the world, and our bodies. However, God’s good and merciful will is carried out when he strengthens and keeps us ﬁrm through his word and our faith to the end.
