Dispensational Truth is that which has to do with the different dispensations. The cycle of time is supposed to be for 7000 years: 4000 years before Christ and 3000 years after Christ. Before that it was eternity; after that it is the eternal state again.
God always existed. We may not understand this, but we believe it because God says so. Jehovah means the Eternal One. He is infinite. He does not need to explain everything to us. If we understood everything we would be His equal. We are finite; God is infinite. The wonderful thing is that God deigns to have a redeemed company with Him throughout eternity. But they must be redeemed (John 3:1616For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. (John 3:16)). He will have a heavenly people and He will have an earthly people; hence the need of having a knowledge of the dispensations.
