Believers are the aroma of Christ to those around them

Scripture reference

2 Corinthians 2:14–16 (ASV 1901)

14But thanks be unto God, who always leadeth us in triumph in Christ, and maketh manifest through us the savor of his knowledge in every place. 15For we are a sweet savor of Christ unto God, in them that are saved, and in them that perish; 16to the one a savor from death unto death; to the other a savor from life unto life. And who is sufficient for these things?
