'Exists' in the Bible

But if God so clothes the grass of the field, which today exists, and tomorrow is thrown into the oven, won't he much more clothe you, you of little faith?

But if this is how God clothes the grass in the field, which today exists, and tomorrow is cast into the oven, how much more will he clothe you, O you of little faith?

For this Hagar is Mount Sinai in Arabia, and answers to the Jerusalem that exists now, for she is in bondage with her children.

Without faith it is impossible to be well pleasing to him, for he who comes to God must believe that he exists, and that he is a rewarder of those who seek him.
