The word 'hallow' is the verb form of 'holy.'
To hallow something means to sanctify it, to set it apart as holy.
God and His name are already holy, so the prayer here is that His name would be seen and recognized for the uniquely holy thing that it is.
Let God be glorified in heaven and on earth.
Let His name be appreciated.
Let His greatness and goodness be received and honored everywhere.
God has revealed Himself by many names which have a healing benefit.
The Lord Who Heals, He is our healer.
The Lord Will Provide, He has seen our needs and has provided for our health.
The Lord My Banner, He is our victory over sin, sickness and everything that stands against us.
The Lord My Peace, He is our wholeness, in Him we made complete body, soul and spirit.
The Lord My Shepherd, He takes care of us and we do not lack for any good thing.
The Lord My Righteousness, He qualifies us to receive every blessing and promise of God.
These and many other names show the holiness of God.
No one else is like the Lord;
No one else can do the things He can do.
As we pray the Lord's Prayer, let these names become holy in our hearts.
Honor these names and receive them inwardly.
Give glory to Him by these names, affirming all their healing significance.
