"Blessed be the God and Father of our Lord Jesus Christ, the Father of
mercies and God of all comfort." 2 Corinthians 1:3
Verse 4 tells us when and what it enables us to do,
"who comforts us in all our tribulation, that we may be able to comfort
those who are in trouble, with the comfort with which we ourselves are
comforted by God."

So we see that comfort comes from God our Father. We also see that the words
of our Lord Jesus Christ are comfort.

In Matthew 9:20-22 we see Jesus giving comfort to a suffering woman whose
faith in Him knew that by touching His garment, she would be healed.
"But Jesus turned around, and when He saw her He said, 'Be of good cheer,
daughter; your faith has made you well.'" Vs. 22

Luke 7:11-16 tells us the comfort and mercy Jesus gives to a widow whose son
had died,
"Then He came and touched the open coffin, and those who carried him stood
still. And He said, 'Young man, I say to you, arise.' And he who was dead
sat up and began to speak, And He presented him to his mother."
Vs. 14-15

John 14:1-4, Christ Jesus comforts His disciples,
"Let not your heart be troubled; you believe in God, believe also in Me.I go
to prepare a place for you." Vs. 1-2
In Vs. 16-17 Jesus tells them,
"And I will pray the Father, and He shall give you another Comforter, that
He may abide with your forever; even the Spirit of truth."
Jesus gives them assurance;
"I will not leave you comfortless." Vs:18

John Chapters 13-16 is Jesus' final discourse to His disciples,
"These things I have spoken to you, that in Me you may have peace. In the
world you will have tribulation; but be of good cheer, I have overcome the
world." John 16:33

The Scriptures themselves give comfort:
"For whatever things were written before were written for our learning, that
we through the patience and comfort of the Scriptures might have hope."
Romans 15:4

The Greek word for comfort is PARAKLESIS, it means a calling to one's side;
hence, either an exhortation, or consolation, comfort.

Verse 4 of our opening verses tells us of God's comfort in tribulation and
in our verse above Jesus tells us we will have tribulation. So then we are
give comfort to others who are in trouble.
In The Amplified Bible verse 4 says,
"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."

We are to walk beside, to console, to encourage, to bear each other burdens,
to do what is needed. Here are VERY few examples, but Scripture is a fount
of them.

Paul in Acts 20:35,
"I have shown you in every way, by laboring like this, that you must support
the weak. And remember the words of the Lord Jesus, that He said, 'It is
more blessed to give than to receive.'"

Paul in Romans 15:1,
"Now we who are strong ought to bear the weaknesses of those without
strength and not just please ourselves."

James 1:27,
"Pure and undefiled religion before God and the Father is this: to visit
orphans and widows in their trouble, and to keep oneself unspotted from the
world."

There is the parable of the good Samaritan in Luke 10:29-37
"But a certain Samaritan, as he journeyed, came where he was. And when he
saw him, he had compassion on him, and went to him and bandaged is wounds,
pouring on oil and wine; and he set him on his own animal, brought him to an
inn, and took care of him." Vs. 33-34

1 Peter 3:8,
Finally, all of you be of one mind, having compassion for one another; love
as brothers, be tender hearted, be courteous."

Thank you Lord God for Your great love that comforts us in our trials and
tribulations. Cause our hearts to love unselfishly that we may be a comfort
to those in need. We thank you for that wonderful comforting truth of 
Romans 8:28,
"For we know that all things work together for good to those who love God,
to those who are called according to His purpose."
Amen
