What does the Bible say about how to approach God?

Since sin entered the world, humanity has sought ways to approach and please a holy God. Leviticus 17:11 emphasizes that the life of the flesh is in the blood, and it is the blood of Christ, the holy and spotless Lamb of God, that provides the necessary sacrifice. This sacrificial death on Calvary reconciles us to God, offering a complete atonement for our sins. It is through Christ's atoning work that we can come boldly to the Father, knowing our acceptance is through His blood alone.
