"OMG!"

I've been asked, "So when you text/say omg is that a sin?"

OMG is typically a shortening of "O, My God". When you use God's name like this it is taking something special and holy and treating like it is just another generic word to express excitement. It's like taking mom's china on a picnic. This is an example of taking the Lord's name in vain. (2nd Commandment - Ex. 20:3-8 - Jesus' summary in Matt. 22:37-38) Yes, this is sin. 

As is the case with this sin and others Jesus paid for it on the cross. You are forgiven. Your guilt is removed. You have the freedom to reserve Jesus' name or God's name for special moments of prayer, singing, praise, Bible reading, sharing Him with a friend, etc.  

2 Corinthians 5:14-15

For Christ’s love compels us, because we are convinced that one died for all, and therefore all died. 15 And he died for all, that those who live should no longer live for themselves but for him who died for them and was raised again.
