What does the Bible say about the prayers of saints?

In Revelation 5:8, the prayers of saints are depicted as golden vials full of odours, symbolizing the sweetness and holiness of these prayers before God. This imagery is rooted in Old Testament practices—particularly in the use of incense at the altar, which represented the prayers of God's people ascending to Him. Psalm 141:2 echoes this, stating, 'Let my prayer be set before You as incense.' The prayers of believers are thus portrayed as an essential part of worship, ascending to God and finding acceptance through Christ, the ultimate mediator.
