'Exists' in the Bible

And not a creature exists that is concealed from His sight, but all things are open and exposed, and revealed to the eyes of Him with whom we have to give account.

But without faith it is impossible to [walk with God and] please Him, for whoever comes [near] to God must [necessarily] believe that God exists and that He rewards those who [earnestly and diligently] seek Him.

Remember your leaders [for it was they] who brought you the word of God; and consider the result of their conduct [the outcome of their godly lives], and imitate their faith [their conviction that God exists and is the Creator and Ruler of all things, the Provider of eternal salvation through Christ, and imitate their reliance on God with absolute trust and confidence in His power, wisdom, and goodness].
