The way you speak about God reveals the kind of relationship you have with Him. ( Matt 12:24, "Out of the fullness of the heart, the mouth speaks.") As a new Christian I was content to talk about God in the third person - like everyone else in my church. The classic hymns also usually talk about Him in the third person. But eventually I realized that this is treating Him like an "it" instead of a person. If that doesn't work for your family and friends, what makes you think it will work for God?
God doesn't want to hear you say, "I love Him." He wants to hear you say, "I love You!"
