Signs of the Cross
The burial of Jesus has significance in and of itself as it displays the Father's approval of Jesus Christ and his work.
The flow of blood and water from Jesus' side further reveals our Lord's humanity, death, and efficacy of his propitiatory offering.
That Jesus' bones were not broken reveals the Father's regard for his Son, preventing further indignity.
The Father was silent as His Son died, but as soon as Jesus' lips fell silent the Father spoke by profound deeds.
