We are never truly alone because God is always with us.

For He Himself has said, "I will never leave you nor forsake you." (Hebrews 13:5)

Casting all your care upon Him, for He cares for you. (1 Peter 5:7)

Yea, though I walk through the valley of the shadow of death, I will fear no evil; for You are with me; Your rod and Your staff, they comfort me. (Psalm 23:4)

And the LORD, He is the one who goes before you. He will be with you, He will not leave you nor forsake you; do not fear nor be dismayed. (Deuteronomy 31:8)
