There was a time when we heard people say"We need to do away with pictures of Jesus on the cross because He's risen & no longer there. Back then I agreed.
But you know what happened to those that did? They quit thinking about Jesus on the cross dying for their sins & started thinking about themselves.
The older folks who left the church were right.... we should have left it the way it was. The REAL reason it was changed was because WE changed, & no longer wanted it. We were fooled.
The greatest reminder of the Lord is His word and prayer. If a person has trouble remembering the cross they need to get into God's word more and pray for the Holy Spirit's help.
It's so simple but human nature always thinks it knows better.
