Was it your “ right to interpret God’s word” that you used to come up with Dispensationalism®?
"If ye have heard of the Dispensation of the grace of God which IS GIVEN ME TO YOU-WARD.." Eph. 3:2,3,5,6,9.
"...A Dispensation of the Gospel is committed unto me." 1 Cor. 9:17.
"Wherefore I am made a minister, according to the Dispensation of God which is given me for you, to fulfill the word of God." Col. 1:25.
"That in the Dispensation of the fulness of times he might gather together in one all things in Christ..." Eph. 1:10.
As you can clearly see, Paul wrote of dispensations. You can deny it, but it doesn't change that fact.
If you would study your Bible, you would not be embarrassing yourself by claiming I came up with it. Jesus Christ came up with it. And revealed it to Paul. Who revealed it to the Church the Body of Christ.
Acts 17:11 These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.
