Some illustrate God as H2O, which can be of three types – solid (ice), liquid (water), and gas (steam). At the same time, others illustrate the Trinity as an egg, which is a part shell, part white, and part yoke.

All of these analogies attempt to explain how one entity can be three persons at the same time. However, without a definition, the effect of such illustrations is ineffective. Illustrations should only be used to demonstrate a definition.

The Trinity can be defined as follows; 

A BEING is the quality or essence that makes you ‘what’ you are, and the PERSON is that quality or essence that makes you ‘who’ you are. We as humans are one being with one person, but God is one being with three persons – the Father, the Son, and the Holy Spirit.

The Word Trinity comes from the word Tri + unity, Tri meaning three, and unity meaning one. This means there is a oneness in the Character of God, but also a distinction in the three persons.

The Bible is clear when it states that there is only one God. However, it also reveals that this God has three personal distinctions in His complex nature, which is traditionally referred to as the three persons in the Godhead. Each person of the Godhead is distinct from the other but never acts independently.

The Father is not the same person as the Son; the Son is not the same person as the Holy Spirit, and the Holy Spirit is not the same person as Father. 

They are distinct persons; yet, they are together one God. 

They are in absolute perfect harmony as one Being. They are co-eternal, co-equal, and co-powerful. If anyone of the three persons were removed, there would be no God. 

The importance of each distinct role and function of the persons of the Godhead is apparent in our salvation. The Father chooses who will be saved (Eph. 1:4); the Son redeems them (Eph. 1:7), and the Holy Spirit seals them (Eph. 1:13).
