When you forget your past, you drop your old cross.
Jesus then said to his disciples,
MATTHEW 16:24-26
“If any man will follow me, let him forsake himself: and take up his cross, and follow me.
For whosoever will save his life, shall lose it: and whosoever shall lose his life for my sake, shall find it.
For what shall it profit a man though he should win the whole world, if he lose his own soul? or what shall a man give for recompense of his soul?”
