It is often used as an "Invitation Hymn" --
And, as such, is especially appropriate for a Hymn which is sung during Passover and Easter (Resurrection Sunday).
Why?
Well, because The Lord God Jesus Christ shed His blood as He died in order to provide everyone an opportunity to accept His substitute sacrifice for their sins.
Why is this important?
Because, unless a person is "washed in the blood of Jesus" he / she can not spend eternity with Christ, God the Father, the Holy Spirit, and the believers in heaven.
Think about this as you sing along with this Hymn.
