When I struggle, these are some of my “go to” passages.  I encourage you to meditate upon them for God’s glory and your edification.

Psalm 37:4 Delight yourself in the Lord, and He will give you the desires of your heart. 5 Commit your way to the Lord;  trust in Him, and He will act. 6  He will bring forth your righteousness as the light, and your justice as the noonday. 7  Be still before the Lord and wait patiently for Him; fret not yourself over the one who prospers in his way, over the man who carries out evil devices! 8  Refrain from anger, and forsake wrath!  Fret not yourself; it tends only to evil. 9  For the evildoers shall be cut off, but those who wait for the Lord shall inherit the land.

Psalm 34:4 I sought the Lord, and He answered me and delivered me from all my fears.

Psalm 46:1 God is our refuge and strength, a very present help in trouble. 2 Therefore we will not fear though the earth gives way, though the mountains be moved into the heart of the sea, 3 though its waters roar and foam, though the mountains tremble at its swelling.

Habakkuk 3:17 Though the fig tree should not blossom, nor fruit be on the vines, the produce of the olive fail and the fields yield no food, the flock be cut off from the fold and there be no herd in the stalls, 18  yet I will rejoice in the Lord;  I will take joy in the God of my salvation. 19 God, the Lord, is my strength; He makes my feet like the deer’s; He makes me tread on my high places.

1 Peter 5:8 Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour. 9  Resist him, firm in your faith, knowing that the same kinds of suffering are being experienced by your brotherhood throughout the world. 10 And after you have suffered a little while, the God of all grace, who has called you to his eternal glory in Christ, will himself restore, confirm, strengthen, and establish you. 11  To him be the dominion forever and ever. Amen.

1 Corinthians 15:10 By the grace of God I am what I am, and His grace toward me was not in vain. On the contrary, I worked harder than any of them, though it was not I, but the grace of God that is with me.

Romans 8:31 If God is for us, who can be against us? 32  He who did not spare his own Son but gave Him up for us all, how will He not also with Him graciously give us all things?
