Courage

Be strong and very courageous." and "Do not be afraid or
discouraged.": Those were commands to Joshua, orders--not emotions.
He was instructed not to feel, but to do.

We typically think of love, courage, fear, and such as emotions.
They are, in truth, decisions that are accompanied by emotions.

Now, a decision requires information. And the right information
makes the decision easier to hold to when it is tested.
  

Be strong and very courageous. Obey all the laws Moses gave you. Do
  not turn away from them, and you will be successful in everything
  you do. Study this Book of the Law continually. Meditate on it day
  and night so you may be sure to obey all that is written in it. Only
  then will you succeed. I command you--be strong and courageous! Do
  not be afraid or discouraged. For the LORD your God is with you
  wherever you go." (Josh 1:7-9 NLT)

The Right Time

You see, at just the right time, when we were still powerless,
  Christ died for the ungodly. Very rarely will anyone die for a
  righteous man, though for a good man someone might possibly dare to
  die. But God demonstrates his own love for us in this: While we were
  still sinners, Christ died for us. Since we have now been justified
  by his blood, how much more shall we be saved from God's wrath
  through him! For if, when we were God's enemies, we were reconciled
  to him through the death of his Son, how much more, having been
  reconciled, shall we be saved through his life! (Rom 5:6-10 NIV)

Can I Get one Amen?

I have little tolerance for negative, critical, fault-finding,
judgmental people. The emotions they incite can be a very
detrimental spiritual distraction.

For me, it feels like trying to play in a
band with an off-rhythm drummer: Very difficult to ignore! If you had to
focus on the rhythm and count it out: 1-2-3-4, 1-2-3-4, 1-2-3-4...

"Count it out" in spiritual terms: Do not as much as you are able
allow them to pull your attention from the Lord and your relation-
ship with Him, the source of your spiritual rhythm and harmony.

  Don't let anyone look down on you because you are young, but set an
  example for the believers in speech, in life, in love, in faith and
  in purity. Until I come, devote yourself to the public reading of
  Scripture, to preaching and to teaching. Do not neglect your gift,
  which was given you through a prophetic message when the body of
  elders laid their hands on you. Be diligent in these matters; give
  yourself wholly to them, so that everyone may see your progress.
  Watch your life and doctrine closely. Persevere in them, because if
  you do, you will save both yourself and your hearers. (1 Tim 4:12-16 NIV)

Regardless

One of our basic human needs is to be understood. It is not just a
"nice thought". It is a need because God created us that way.

Remember that even if no one else understands your circumstances (or
cares), God does. Where you are and what you have done is no
surprise to Him. He understands. And He loves you--regardless.
  

You have had enough in the past of the evil things that godless
  people enjoy--their immorality and lust, their feasting and
  drunkenness and wild parties, and their terrible worship of idols.
  Of course, your former friends are very surprised when you no longer
  join them in the wicked things they do, and they say evil things
  about you. But just remember that they will have to face God, who
  will judge everyone, both the living and the dead. (1 Pet 4:3-5 NLT)

Relationship

As far as how we interact with God: It is all about relationship.

Remember when you were "in love"? You wanted to be with that person,
know everything about them, make everything all right for them. The
world was a better, brighter place because they were in it.

That is how God feels about us (John 3:16). Do you feel that way
about your relationship with Him? Really think about that today.
  

  For this reason, since the day we heard about you, we have not
  stopped praying for you and asking God to fill you with the
  knowledge of his will through all spiritual wisdom and
  understanding.  And we pray this in order that you may live a life
  worthy of the Lord and may please him in every way: bearing fruit in
  every good work, growing in the knowledge of God,  being
  strengthened with all power according to his glorious might so that
  you may have great endurance and patience, and joyfully giving
  thanks to the Father, who has qualified you to share in the
  inheritance of the saints in the kingdom of light. (Col 1:9-12 NIV)

Focus

Some days (weeks, months, years) are just tough. If you are in one,
do not lose sight of your hope in the struggle.
  

And I heard a loud voice from the throne saying, "Now the dwelling
  of God is with men, and he will live with them. They will be his
  people, and God himself will be with them and be their God. He will
  wipe every tear from their eyes. There will be no more death or
  mourning or crying or pain, for the old order of things has passed
  away." (Rev 21:3-4 NIV)

Life

Some people say, "Life is a bowl of cherries." I say that it can
feel like a series of breakings sometimes. And in that case, it is
easy to look for someone or something to blame for our troubles.

A problem can come unbidden and be unavoidable. But even then, the
first place we should look is to our foundation, our relationship
with God. Is it strong and secure, or is it shaky and unstable?

I believe that we really can survive anything with God--and I say
that from my experience, not as rhetoric or cliche. He can turn even
a problem that we created to our good in the end.

  I will show you what he is like who comes to me and hears my words
  and puts them into practice. He is like a man building a house, who
  dug down deep and laid the foundation on rock. When a flood came,
  the torrent struck that house but could not shake it, because it was
  well built. But the one who hears my words and does not put them
  into practice is like a man who built a house on the ground without
  a foundation. The moment the torrent struck that house, it collapsed
  and its destruction was complete." (Luke 6:47-49 NIV)
