There is a quote that says, "Everything will be okay in the end. If it's not okay, then it's not the end."
This holds much truth. The end for a Christian is eternity with God. Meanwhile, we shall not fear.
Jesus said, Therefore do not be anxious about tomorrow, for tomorrow will be anxious for itself. Sufficient for the day is its own trouble.- (Matthew 6:34 ESV)
The Lord has said that He will never leave us nor forsake us. (Hebrews 13:5). Surely He is with you in times of trouble and in times of gladness. He is with you on the mountain top and in the valley.
Everything truly will be okay in the end. If you have any doubts, assure your heart and reread the end of the book.
Jesus, may our hopes and our fears rest in you alone. You hold all things together and in you all things are complete. Amen.*
*Colossians 1:17
