How can I cope with the grief I feel?

Ecclesiastes 3:4
(There is) a time to cry and a time to laugh. A time to grieve and a time to dance.

Grief has its own season, but then it is time to move on to another. God wants us to wipe our tears, move on, and be redemptive to other grieving people.

What will help overcome my grief?

2 Corinthians 1:3
All praise to the God and Father of our Lord Jesus Christ. He is the source of every mercy and the God who comforts us.

Psalm 23:4
Even when I walk through the dark valley of death, I will not be afraid, for you are close beside me. Your rod and your staff protect and comfort me.

Matthew 5:4 (words of Jesus)
God blesses those who mourn, for they will be comforted.

God knows we grieve, understands our sorrow, and comforts us. He does not promise to preserve us from grief, but to help us through it.

1 Thessalonians 4:13-18
And now, brothers and sisters, I want you to know what will happen to the Christians who have died so you will not be full of sorrow like people who have no hope. For since we believe that Jesus died and was raised to life again, we also believe that when Jesus comes, God will bring back with Jesus all the Christians who have died. I can tell you this directly from the Lord: We who are still living when the Lord returns will not rise to meet him ahead of those who are in their graves. For the Lord himself will come down from heaven with a commanding shout, with the call of the archangel, and with the trumpet call of God. First, all the Christians who have died will rise from their graves. Then, together with them, we who are still alive and remain on the earth will be caught up in the clouds to meet the Lord in the air and remain with him forever. So comfort and encourage each other with these words.

Take hope that for the Christian will be no more grief in heaven.

Genesis 23:1-20

When Sarah was 127 years old, she died at Kiriath-arba (now called Hebron) in the land of Canaan. There Abraham mourned and wept for her. Then, leaving her body, he went to the Hittite elders and said, “Here I am, a stranger in a foreign land, with no place to bury my wife. Please let me have a piece of land for a burial plot.” The Hittites replied to Abraham, “Certainly, for you are an honored prince among us. It will be a privilege to have you choose the finest of our tombs so you can bury her there.” Then Abraham bowed low before them and said, “Since this is how you feel, be so kind as to ask Ephron son of Zohar to let me have the cave of Machpelah, down at the end of his field. I want to pay the full price, of course, whatever is publicly agreed upon, so I may have a permanent burial place for my family.” Ephron was sitting there among the others, and he answered Abraham as the others listened, speaking publicly before all the elders of the town. “No, sir,” he said to Abraham, “please listen to me. I will give you the cave and the field. Here in the presence of my people, I give it to you. Go and bury your dead.”
Abraham bowed again to the people of the land, and he replied to Ephron as everyone listened. “No, listen to me,” he insisted. “I will buy it from you. Let me pay the full price for the field so I can bury my dead there.” “Well,” Ephron answered, “the land is worth four hundred pieces of silver, but what is that between friends? Go ahead and bury your dead.” So Abraham paid Ephron the amount he had suggested, four hundred pieces of silver, as was publicly agreed. He bought the plot of land belonging to Ephron at Machpelah, near Mamre. This included the field, the cave that was in it, and all the trees nearby. They became Abraham’s permanent possession by the agreement made in the presence of the Hittite elders at the city gate. So Abraham buried Sarah there in Canaan, in the cave of Machpelah, near Mamre, which is at Hebron. The field and the cave were sold to Abraham by the Hittites as a permanent burial place.

Participate in the process of grief. Take time to personally mourn, but also become involved in the necessary steps to bring closure to your loss. We grieve because we have had a positive experience - what we lost was important to us. Getting involved in the process of grief is a way of honouring what was meaningful.
