Most of the time, I heard Christians mention the word God, God this and God that............... I feel strange that they use the word Jesus less than God. Though most of the time, Jesus and God are interchangeable. After a little bit investigation, I found that they use God more is because the word God is general, more acceptable to anyone; God can be the God of any religion that believe in God. If you say Jesus, it must mean the Jesus of Christianity.
