It’s obvious you care a great deal for your friend. We know that God desires all to come to Him and He answers prayer, so I’m joining you in asking Him to bring Steven to a saving faith in Jesus. I believe there is great power in our agreeing together in a prayer like this, and we must trust that God will answer according to His promise. I’m praying for you, too, that the Lord may comfort, strengthen, and uphold you during this time. Grace and peace to you!
