1 Thessalonians 4:13-18
Brothers (and sisters) we do not want you to be ignorant about those who fall asleep, or to grieve like the rest of men, who have no hope. 14We believe that Jesus died and rose again and so we believe that God will bring with Jesus those who have fallen asleep in him. 15According to the Lord's own word, we tell you that we who are still alive, who are left till the coming of the Lord, will certainly not precede those who have fallen asleep. 16For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. 17After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever. 18Therefore encourage each other with these words.
2 Corinthians 1:3-4
Praise be to the God and Father of our Lord Jesus Christ, the Father of compassion and the God of all comfort, 4who comforts us in all our troubles, so that we can comfort those in any trouble with the comfort we ourselves have received from God.
1 Peter 5:6-7
"Humble yourselves, therefore, under God's mighty hand, that he may lift you up in due time.7Cast all your anxiety on Him because HE cares for you."
And of course, the important two from Matthew...
Matthew 11:28 and the one of the be-attitudes Matthew 5:4 (respectively):
"Come to me, all you who are weary and burdened, and I will give you rest."
"Blessed are those who mourn, for they will be comforted."
Jesus knows OUR LOSS, as with his friend Lazarus, as Mary & Martha also knew and then Jesus' own mother, Mary, who knew this pain, this grief, this unbearable sorrow...
If you need more verses for COMFORT in GRIEF or LOSS or SADNESS, please visit the site above ENCOURAGING BIBLE VERSES or maybe FOCUS ON THE FAMILY COUNSELING can guide you or point you in the right direction or for an article, you can try (because I did not have much success in getting it) 15 Comforting Bible Verses for Grief by Josh Wiley (but it sounds great)
BUT THE IMPORTANT THING IS TO CHANGE THIS WORD INTO YOUR PRAYER or A PRAYER FOR ANOTHER YOU MAY KNOW DEALING WITH A LOSS or better said, not able to cope & deal with the grief and the loss of a loved one...
I know, I've been there before and I'm still dealing with a recent loss (on my blog) of a very special friend from the end of last year, that is why these verses are so clear today... I needed them. I needed to identify with how his mother must feel today... as Mary with Jesus... on the day that she gave birth to her son. I needed to have words to encourage her in her pain today... and mine.
So let's not give the enemy an edge to defeat us any longer, WE ARE victorious through Jesus Christ and He wants to give us (S.W.A.P) His peace, His Comfort, His Hope for all eternity by living life to the fullest in honor of those we love!!!
"For I consider that the sufferings of this present time are not worthy to be compared with the glory that is to be revealed to us." Romans 8:18

NOW LET US PRAY for ONE ANOTHER
Please refrain from comments but use this for PRAYERS or changing a scripture for anyone that may need your prayers, because sometimes the words just don't come to us when our hearts are heavy and we need someone else. ***
[That's the role of the Holy Spirit, living inside each one of us, who knows Jesus as Our Lord & Savior (if you don't yet or perhaps have wandered away or closed that door in anger at God, it's TIME to come back and PRAY once more to receive Him... click HERE and allow them to walk you through this and lead you in this PRAYER)]
***Actually, that's why Jesus sent His Holy Spirit to remain with us...so call on the Holy Spirit to fill you and speak for you... if you need prayer, you are more than welcome to leave your prayer request (if you can, it's preferred as a prayer also).
Added note: grief or sense of loss is for more than just the loss of a loved one as in death, passing from this life into a better life with God eternally. We can pray together about any of these losses or griefs. I'm sorry if I was leaning towards only one... we all need prayer as we grieve any loss.
