Psalm 49:7–No man can by any means redeem his brother or give to God a ransom for him.
We can try and persuade, demonstrate, beg, and plead, but we cannot force someone else into a relationship with God. Each person is responsible to God for their relationships with Jesus Christ. We can (and should) pray for them, but we cannot do it for them.
Lord, please continue to work in the lives of the others I know. I pray You will show them their need of You since only You can save them.
