Have you ever heard of Tod Friel?  He is a Hermaneutics teacher.  Hermaneutics is the study of how to interpret the Bible. Here is a highlight of what I learned from Todd.

God verbally talked to Moses through the burning bush and to many others in that same way.  But today God speaks to His children through the Bible for the Bible is the word of God, and proper interpretation is a must.  For example, Romans 16:16 says " greet one another with a holy kiss" , And 1st Peter 5:14 also says " greet one another with a holy kiss.  But we shouldn't go up to brothers and sisters today and just kiss them.  That was the cultural way of greeting in the first century.  We should take the principle of greeting fellow Christians in holiness and purity and apply it to our culture.  So, that would be a holy hand shake or a holy hug.  

Your friend in christ
