Many of us had doubts, for sure. Even the widow of Zarephath also had doubts. Her son had been struck with a lethal illness. In her despair she cried out, "Have you come to me to bring my sin to remembrance, and to kill my son?" (1 Kings 17:18). But God had other plans!
We serve a God who is mightier than the struggles we inherit and who is full of the desire to forgive, love, and heal the brokenness that rises up between us and Him. God is present in the places where our fears live. Love swims against the current of life's false fears.
The Bible also tells us that we should not fear. God is with us. Don't be discouraged, for He is our God. He will strengthen you and help you. He will hold you up with His victorious right hand (Isaiah 41:10).
