What is the Gospel? (in 140 characters or less) [a throwback from a couple months]
Jesus is God’s promised King. Repent of independence & depend on His life, death, and resurrection. Then you shall live in His kingdom.
Why must God be a Trinity?
God, being perfect in every way, must delight in everything that He does, for everything that He does demonstrates His perfection. He's glorious and demonstrates His glory through the goodness of all His work. He requires nothing - He's dependent on no one or no thing, for there was nothing before Him. God the Father, Creator, must exult in Himself so that He receives the just delight and praise He's due for His goodness. However, in order for Him to glory justly in the perfection of His wisdom (in which all that He has done has been done), He must be able to objectively regard such work and the perfect wisdom in which it was done. Thus, He must be more than one person, separate in order to give due compensation to the Father Who created all in His perfect wisdom which "The LORD possessed...in the beginning of his way, before his works of old" (Prov. 8:22). The second person of the Godhead is the Son Who can give His Father the perfect praise and love which the Father deserves. This love relationship between the Father and the Son is perfect in that the Son gives God-worthy praise of which only God is capable of giving and the Father receives God-worthy praise which only God ought receive and by which justice is satisfied (He receives from the Son the full due of His goodness). This love-forged relationship which they have is so intense, as their love for one another is perfect, that the Spirit they share is God too. For instance, when a group of people are united in some cause they are said to be of the same spirit. In the realm of education this might be called "school-spirit." The group is unified with a similar mindset/focus. Now obviously in the case of the Father and the Son, their understanding of one another is as perfect as their selves. And so this Spirit is perfect to the extent that He is fully God too. Thus, the Father and Son are of one Spirit which proceeds from them both. Consider the following to better understand the Son's relationship to the Father.
Imagine two books.... That is, you made an act of imagination and as a result you had a mental picture. Quite obviously your act of imagining was the cause and the mental picture the result. But that does not mean that you first did the imagining and then got the picture. The moment you did it, the picture was there. Your will was keeping the picture before you all the time. Yet that act of will and the picture began at exactly the same moment and ended at the same moment. If there were a Being who had always existed and had always been imagining one thing, his act would always have been producing a mental picture; but the picture would be just as eternal as the act. (C.S. Lewis)
In this relationship of three, the perfection of the Godhead is maintained. Only in a trinity can God be just and perfect (One is unjust, two lacks perfect love, more than three is impossible as each would be imperfect).
