"You cannot drink the cup of the Lord and the cup of demons; you cannot partake of the Lord’s table and of the table of demons." I Corinthians 10:21.
That was the Apostle Paul speaking to the Corinthian Christians who were going back and forth between the Lord's table and the table of demons. These Christians would partake the the Lord's super, a sure sign that they had believed in Christ, justified and sanctified by the blood. Every time they ate the communion, they proclaimed the death and resurrection of Christ and reminded themselves of what the Cross stood for. However they would also still fully participate in the pagan festivals and sacrifices that took place in their city drinking and eating food offered to idols in honor of these idols. This they were doing before they got saved.
So Paul called them to order letting them know it was not acceptable to do both. Either they belonged to Christ or they belonged to the devil. They had to choose between their old paganistic traditions and their new Christian traditions. It was not acceptable to do both.
Many of us profess Christianity, in fact we are born again and yet oscillate between our old lifestyles and the new. Indeed in Christ we are "a new creation, the old has passed, the new has come", but is that really true of the lives we still lead? Do people who knew our old selves testify that indeed we have changed? Or do we roll the same way we did? We drink like before, we dress like before, we talk like before, we dance like before, and yet say we are "new". Where is the newness? If the only difference between our old selves and new selves is that we go to church on Sundays then we have missed the point.
Real change is expected of us and God has graciously provided the Holy Spirit to help us produce that change. Going back and forth between the old and new is exhausting. We need to take a stand, a stand for Christ in word and in deed. Remember no one can serve two masters, Jesus' words, not mine.
I'll entreat you today to take an inventory of your life as a Christian, then ask yourself which cup you are drinking from. They say you cannot sit on two chairs, you fall through the middle. Pick a chair and position yourself firmly on it. Just pick the one with Jesus emblazoned on! Cheers!!
