What a small little mind you have.
To invoke a deity, in a spiritual sense, means to draw upon its divine archetype for inspiration. That needn't have anything to do with worship, although it can, if it is your Will. In fact, a belief in the existence of that deity is not even required... but it can strengthen the effects of the invocation. One can be an atheist, or a monotheist, or a polytheist, or a monolotrist, etc... and spiritually invoke, say, Athena... to draw into themselves and strengthen within them the attributes and characteristics that Athena represents, such as wisdom and matters of war. A Christian could even do such, without betraying their Faith, because they wouldn't even have to believe Athena exists to strengthen within themselves her dominant, primary characteristics. In fact, Christians can invoke the power of other spiritual beings within their own Pantheon for inspiration, such as Archangel Michael, or the Virgin Mary (as the Catholics do) without betraying their Lord Christ, Jesus of Nazereth.
If I were to invoke Jesus, as all Christians should become proficient at, I would be choosing to strengthen my feelings of unconditional love, and humility, and empathy, and kindness.
Yet I have a difficult time believing that you are so commited to your Lord Jesus when you so obviously fail to invoke his dominant characteristics into your weltanschauung. Otherwise you would spend less time here spreading such ignorant and mindless hate and douchebaggery.
