Most Christians know that Jesus died on the cross but more than half cannot tell you why He had to die. Take time to share the Gospel of Christ even to those that are believers.  Many are too ashamed to admit they don’t know why they believe what they believe; they become lukewarm or cold and are drawn back into the world because of lack of knowledge and understanding.  Some Churches, are more concerned about tithes and offerings than the salvation of the flock.  If you are not learning in the Church service atmosphere, join a spirit led Bible Study group that can learn and grow in Christ.
