Hallel means to say that something or someone is great. Who do you say is great? Who do you promote in your life? When we 'Hallel Yahweh' we train our hearts in a God orientation.
Who is in your life today that makes your heart flow with thanksgiving to the Lord? If you have a friend or group of friends who faithfully follow the Lord and remain steadfast year after year, take the time to tell them what treasured friends they are.
