What we have now is only a sample

For now we see in a mirror dimly, but then face to face. (1 Corinthians 13:12 ESV)

 Even God had a hard time getting the children of Israel out of the idolatry of Egypt and had to lead them through Moses, with the Law as their schoolteacher, by rituals and material object lessons—the Tabernacle, the Ark, animal sacrifices, and the blood of beasts.
 These were types and shadows, mere pictures of the spiritual realities and eternal verities He was trying to lead them into. He had to take what they understood, the things with which they were familiar in the religions of Egypt and other heathen nations around them, in a fatherly attempt to audio-visualize for them the genuine spiritual truths of the mature adult worship of God Himself
 Paul goes even further on in his prediction to the Corinthians says that the time is coming when we shall see Jesus face to face, and we’ll put away even these childlike gifts of communication in the Spirit. Even what we have now is only a sample of glorious realities to come.
 In the Old Testament were the illustrations; in the present New Testament time are the spiritual truths which we have now by faith alone. But when Jesus comes again, we shall see Him as He is, and be literally like Him, face to face, actually experiencing the fullness of the realities of God and the world to come.
“But when the perfect comes, the partial will pass away.” (1 Corinthians 13:10) —David Brandt Berg [1]

 No man gives anything acceptable to God until he has first given himself in love and sacrifice. —A.W. Tozer
