We all need to be encouraged every once in a while. While you say words of encouragement to your friend who needs them, you can also tell God about what is happening. As you say the following words of prayer, your friend will feel more alive with an uplifted spirit.
Father God, you are the source of all encouragement and consolation. Your presence in our lives gives us strength to further on in life. I speak on behalf of my friend (name of friend). Give them strength when they are weak. Fill them with courage when they get afraid. When they feel alone, watch over them. Let your divine peace overwhelm them. Let nothing ever wear them down. They are coming out victorious. Amen.
