Locke: God's Existence [I.iii.6]

"I grant the existence of God is so many ways manifest, and the obedience we owe him so congruous to the light reason" (pg.29)

I think Locke believes that it is clear that God exist but he is not innate because God is beneficial He believes that god has power and he is able to punish the bad and reward the good.

"God who sees men in the dark, has in his hand rewards and punishments, power enough to call to account the proudest offender. For God, having the inseprable connexion, joined virtue and public happiness together, and made the practice thereof necessary to the preservation of society, and visibly beneficial to whom all with whom the virtous man has to do; it is no wonder that everyone should not only allow, but recommend and magnify those rules to others, from whose observance of them he is sure to reap advantage of him" (pg.29)

This is where he explains how God sees everything and knows everything and has a lot of power. But I think that he is also saying that God is connected with happiness and goodness and these two things become apart of you when you believe in God.
