Acts 2:21 “And everyone who calls on the name of the Lord will be saved.” These words were quoted by a New Testament prophet of an Old Testament prophet.  You and I can quote these same words as the truth remains the same.  There is no other way to spend life eternally in Heaven.  This truth has been since the fall in the Garden of Eden and will never change.  Know this truth.  Believe this truth.  Live this truth.  Tell others this truth.
