Those memorable moments in life are those things that we treasure most. Those things are sometimes the things that help us to continue with our race to survival. When there is nothing left to rely on those good old times they come through for us. But, when new experiences come they become the catalepsy for our continual survival. The new replace the old. Both the new and the old are stored in us and we have the power to bring either out from our hearts.
Matthew 13:52 Then said he unto them, Therefore every scribe which is instructed unto the kingdom of heaven is like unto a man that is an householder, which bringeth forth out of his treasure things new and old.
As Christians, we acquire many experiences that are life learned experiences and such experiences become our strength. When we come to God our lives become enriched with learning experiences and they in turn become knowledge. Knowledge that is stored in our hearts. So, that when we go through hardship we remember the times when His divine intervention took us out or was with us. We have to decide what we do with those experiences that are stored in our hearts, we can not mixed them (Mk.2:21). As Jesus said with the parable of the wine and the skins one will corrupt the other. When we allow the new to surface and come out from our hearts the old will change (Lev. 26:9-11). Now, when the new comes out and transforms the old , the old becomes new. The people of Gibeon feared Joshua and the people of Israel for what they had done to Jericho, that they pretended to journey through the wilderness for a very long with what was new clothing and wines and ended up broken and old things (Jos.9:13). Eventually, the Gibeon people got caught in the lie and so it happens with when one tries to use the old to simulate the new; that was the old way of thinking. God cannot be mocked, one cannot pretend to walk in newness, because when you do the old it will creep up back again (Ro. 7:6). The writer to the Hebrews tells us that the od is ready to pass away (Heb. 8:13), it is wax old. So, we must not stay with the old.
