Jesus rose from the dead on Sunday resulting in THE day of Conquest! When the women visited the tomb they found the soldiers gone and the stone rolled away...and it was empty. When they reported it to the disciples, Peter & John found it empty. Then Jesus started making many post resurrection appearances, first with Mary Magdalene & the other women, then the two disciples on the road to Emmaus, then finally to the disciples in multiple instances starting in the Upper Room. Jesus commissioned His disciples to continue His mission to all the nations of the world in his authority. He then appeared to them over a period of 40 days opening their minds to all the Scriptures said about Him. These 40 days included a trip to Galilee to receive the Great Commission, and then again in Jerusalem He gave them the Great Commission (again!) before blessing them and ascending to Heaven awaiting His second coming.
