In the spring, at the time when kings go off to war, David sent Joab out with the king’s men and the whole Israelite army. They destroyed the Ammonites and besieged Rabbah. But David remained in Jerusalem. 
2 Samuel 11:1

Be self-controlled and alert. Your enemy the devil prowls around like a roaring lion looking for someone to devour. Resist him, standing firm in the faith, because you know that your brothers throughout the world are undergoing the same kind of sufferings. 
1 Peter 5:8-9

Consider him who endured such opposition from sinful men, so that you will not grow weary and lose heart. 
Hebrews 12:3

Finally, be strong in the Lord and in his mighty power.
Ephesians 6:10

Those who hope in the Lord will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.
Isaiah 40:31

Our dear friend Luke, the doctor, and Demas send greetings. 
Colossians 4:14

Do your best to come to me quickly, for Demas, because he loved this world, has deserted me.   
2 Timothy 4:9-10

Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world.
James 1:27

Do not love the world or anything in the world. If anyone loves the world, the love of the Father is not in him.
1 John 2:15

Since, then, you have been raised with Christ, set your hearts on things above, where Christ is seated at the right hand of God.  Set your minds on things above, not on earthly things.  For you died, and your life is now hidden with Christ in God.
Colossians 3:1-2

“Again Jesus began to teach by the lake. The crowd that gathered around him was so large that he got into a boat and sat in it out on the lake, while all the people were along the shore at the water’s edge. The farmer sows the word. Some people are like seed along the path, where the word is sown. As soon as they hear it, Satan comes and takes away the word that was sown in them.  Others, like seed sown on rocky places, hear the word and at once receive it with joy.  But since they have no root, they last only a short time. When trouble or persecution comes because of the word, they quickly fall away.  Still others, like seed sown among thorns, hear the word; but the worries of this life, the deceitfulness of wealth and the desires for other things come in and choke the word, making it unfruitful.  Others, like seed sown on good soil, hear the word, accept it, and produce a crop—thirty, sixty or even a hundred times what was sown.” 
Mark 4:1, 14-20

I have been reminded of your sincere faith, which first lived in your grandmother Lois and in your mother Eunice and, I am persuaded, now lives in you also.  For this reason I remind you to fan into flame the gift of God, which is in you through the laying on of my hands.
2 Timothy 1:5-6
