“For where there is a testament, there must also of necessity be the death of the testator.” Hebrews‬ ‭9:16‬ ‭NKJV‬‬
Jesus is the testator and in order for us to receive the inheritance, of eternal life, Jesus had to go to the cross. If we want to receive the inheritance we must meet three conditions; Repent, Believe and Receive.
