“The next day, the one after Preparation Day, the chief priests and the Pharisees went to Pilate. ‘Sir,’ they said, ‘we remember that while he was still alive that deceiver said, ‘After three days I will rise again.’ So give the order for the tomb to be made secure until the third day.'” (Matthew 27:62-64)

So what happened on Saturday? Jesus’ dead body lay in the tomb. The Pharisees and chief priests knowing well how to be deceivers themselves, thought that the disciples (who were so scared at this time that they had locked themselves behind closed doors) would steal Jesus’ body and say that He rose from the dead.
So, they asked Pilate and he said, “Make the tomb as secure as you know how.” So they put a seal on it and placed guards at the tomb.
How ironic! Unbelievers make sure that the tomb is heavily secure to make sure no one messes with it. Their actions end up making even more sure that no trickery did happen and that Jesus really did rise from the dead!
God works in such wonderful ways that He can even use the actions of total unbelievers to accomplish His will. That’s your God! When things happen that don’t seem to make sense to you, remember who your God is! He is the God who makes all things work for His eternal purposes and the good of His people!
Looking forward to celebrating Christ’s resurrection, just like you,
