How do we know that our sacrifice to God is acceptable?

Paul, in Romans 12, highlights that our sacrifices to God are deemed acceptable when they reflect the mindset of Christ and are offered through Him. Just as the Old Testament sacrifices were given to God for His use, our lives, as 'living sacrifices,' should reflect His character and purposes. This means being set apart for God’s glory and serving others, which is only possible when we recognize that Christ has rendered our efforts acceptable. It is His love and mercy that drive us to serve, ensuring that whatever we do, whether mundane or significant, is pleasing to God.
