He has also set eternity in the human heart

Stop denying the pain

2 Corinthians 12:9-10

Therefore, I'll boast all the more gladly about my weaknesses so that Christ's power may rest on me. That's why, for Christ's sake I delight in weaknesses, I delight in insults, I delight in hardships, I delight in persecutions, I delight in difficulties for when I am weak, then I am strong. When I am weak, his strength is made perfect in me.

God will bring purpose out of your pain

1 Peter 1:6-7

There is a wonderful joy ahead. Even though you must endure many trials for a little while. These trials will show that your faith is genuine. It is being tested as a fire tests and purifies gold. Though your faith is far more precious than mere gold. So when your faith remains strong through many trials, it will bring you much praise and glory and honor when Jesus Christ is revealed to the whole world.

Romans 8:28

And we know that in all things God works for the good of those who love him, who have been called according to his purpose

Don’t grow bitter

Hebrews 12: 12-15

See to it that no one falls short of the grace of God and that no bitter root grows up to cause trouble and defile many.

Exodus 15:22-25

So Moses brought Israel from the Red Sea; then they went out into the Wilderness of Shur. And they went three days in the wilderness and found no water. Now when they came to Marah, they could not drink the waters of Marah, for they were bitter. Therefore the name of it was called Marah. And the people complained against Moses, saying, “What shall we drink?” So he cried out to the Lord, and the Lord showed him a tree. When he cast it into the waters, the waters were made sweet.
