"I desire that you comfort those who grieve. Stand with those who mourn. Be a friend to those in need. You own My life-giving power. Invest it in those who need My presence in their lives when they are too weak to call upon Me themselves. I will be available to them because of you. When they have no strength to be strong themselves - when there is nothing left in them, when they have no power to come to Me on their own - you carry them to Me in prayer. You point them to My love and mercy. You help them bear the weight of the sorrow that is upon them. Be a friend. Be their advocate as Jesus is yours."
Exodus 17:12 AMP
But Moses' hands were heavy and grew weary. So [the other men] took a stone and put it under him and he sat on it. Then Aaron and Hur held up his hands, one on one side and one on the other side; so his hands were steady until the going down of the sun.
II Cor. 1:3-4 AMP
3) Blessed be the God and Father of our Lord Jesus Christ, the Father of sympathy (pity and mercy) and the God [Who is the Source] of every comfort (consolation and encouragement),
4) Who comforts (consoles and encourages) us in every trouble (calamity and affliction), so that we may also be able to comfort (console and encourage) those who are in any kind of trouble or distress, with the comfort (consolation and encouragement) with which we ourselves are comforted (consoled and encouraged) by God."
Some time ago, I found out that my very good friends had lost both of their sons in an accident. Their loss was beyond my comprehension. Their grief was overwhelming. When I talked to them, all I could do was cry with them and promise to hold them up in prayer. My heart broke for their loss. They not only needed the strength of the Lord, but they needed the strength of others to help them make it through that time. Everything else we do as Christians is hypocrisy if we do not walk with others through times like that, being strong for them when they are too weak to bear the weight of their grief. It is the priority of Jesus to be an advocate on their behalf. It is the way that our Father has called each of us to walk.
Live Your strength through me, Lord,
