To worship Heavenly Father, is to worship Jesus Christ, and the opposite is true. This is what it means to worship the Father in spirit and in truth (John 4:23).
We cannot know Heavenly Father without knowing Jesus Christ and we cannot know Jesus Christ without knowing Heavenly Father. Once we truly know one of them we shall know the other. In saying this, the moment people want to claim they know Jesus Christ, ask them if they know Heavenly Father and if they say No, they have lied about knowing Jesus Christ, even if they do not know it is a lie. The reverse is true, if they claim to know God, the Father in Heaven and they deny Jesus Christ, then they have lied, they know nothing of Heavenly Father.
The basis of to know one we must then know the other is why the first vision with Joseph Smith occurred the way it did. Heavenly Father appearing with his only begotten son, Jesus Christ. Heavenly Father or Jesus Christ abides in the gospel because it gives us the very principles which they both live. The appearance of both the Father and Jesus Christ is because one is not without the other. To know or see one, we must be able to see the other. The event of the First Vision with Joseph Smith is a perfect example. It shows Heavenly Father and Jesus Christ as separate personages, not one personage emanating as one or the other. Since God cannot lie or mislead, then it is truth as given to Joseph Smith. The same applies when believing in Jesus Christ. In order to believe in Jesus Christ, the belief must also involve Heavenly Father.

There is an endless array of claims against Joseph Smith and this Church, so much so, it would be hard to count them, but from time to time, I feel there is a need to address some of these claims, for faith reasons. What would be my reason to address only a few? The reason is to express spiritual common sense and first hand knowledge and experience toward those Anti-Mormon claims, showing the foolishness of them.
There are many other Christians who speak against the use of feelings in regards to faith and the discernment of truth. Some Christians use the Bible to deny the idea that impressions from the Holy Ghost are felt based on the idea that we cannot trust feelings. Others denounce the idea of feelings because it has no basis in fact or logic, claiming that feelings about Mormonism is far too subjective.
