"It will come to pass when you come to the land which the Lord will give you, just as He promised, that you shall keep this service." (Exodus 12:25)
This was God's instruction to Moses for the "Feast of Passover," which they were to celebrate, "for the generations to come." This is an example of what I call, "The God of the Before and the After." He not only spoke to Abraham centuries before of the Exodus from Egypt, He also spoke to Moses of those who would keep this Feast in the, "generations to come," millennia after the Exodus.
The people were in panic mode, and the Blessed Trinity had the nerve to speak of an event which was still 40 years in the future. This is "faith 101." Romans 4 tells us that Our Father, Our Lord Jesus Christ, and the Blessed Holy Spirit is He Who, "....gives life to the dead and calls the things which do not exist as existing." This is a perfect description of what the Bible calls, "The Faith of Jesus."
You and I do not "see" tomorrow, but in Jesus Christ, tomorrow is already here, fulfilled in His Perfect Will and Timing and Fulfilled Promises. Rest.
Father, in Jesus' Name, I do. Amen.
