Of course, the Father is Lord, but also Jesus is Lord. The scriptures are quite clear and explicit in stating that the Father is God, Jesus is God and the Holy Ghost is God.
The Hebrew scriptures always emphasize the 'oneness' of God. I always thought "How can Jesus and the Holy Spirit be God if God is one?"
The answer is in the Old Testament. In Hebrew there are 2 words for 'one' There is the singular 'one' like we use in English, but in Hebrew there is a plural 'one' that indicates the combining of more than one thing but is also described as 'one'
Yachid and Echad are the words in Hebrew and God is always described in the plural 'one' in Hebrew. Never in the singular.
God with us, in the flesh, just like the Hebrew scriptures prophesied.
Of course, it is impossible to have an accurate analogy to describe God as there is nothing like God. We, as human beings cannot really comprehend even the existence of a being that has no beginning or an end. So no analogy really works, but I think of the Godhead much like 'time'. Time has a PAST, a PRESENT and a FUTURE, All of these moments are 100% time, yet they are not the same, yet they all agree and have a place in relation to each other.
