The truth is always the truth. It is just waiting to be discovered.

The truth is the truth. It stands outside of time. It never changes. It remains the same through the centuries. It is only we who change as truth is revealed to us and discovered by us. It was and is and will be always there waiting to be found. God is forever the truth-holder.

“I am the Lord; I do not change."
Malachi 3:6a

"Jesus Christ the same yesterday, and today, and for ever." 
Hebrews 13:8

"Jesus answered, 'I am the way and the truth and the life.'"
John 14:6a
