Although I'm not a pastor, I recently addressed our congregation regarding a traumatic event that occured with my family. Some people ask why bad things happen. This side of Heaven, we simply don't know.
Deuteronomy 29:29
The secret things belong to the Lord our God...
What we do know is that God does not cause these things to happen, but he does allow them.
Lamentations 3:31-33
For men are not cast off by the Lord forever.Though he brings grief, he will show compassion, so great is his unfailing love.For he does not willingly bring affliction or grief to the children of men.
We also know that he expects us to learn and grow through these experiences.
James 1:12
Blessed is the man who perserves under trial, because he has stood the test, he will receive the crown of life that God has promised those who love Him.
James 1:2-3
Consider it pure joy my brothers, when faced with trials of many kinds, because you know that the testing of your faith develops perserverance.
We also need to trust that God is always present during times when we need Him most.
Phillipians 4:7
God's peace, which surpasses all understanding, will comfort your heart and mind through Jesus Christ.
Isaiah 26:3
You will keep in perfect peace him whose mind is steadfast because he trusts in You.
I know that my words provide little comfort in your situation; but, the intention of my post is to offer hope through God's Words. You have a multitude of people praying for you and your family... mine included.
