What hasn't changed: Prepositions all have an object. Prepositions precede said object. Objects of prepositions are nouns or pronouns, NEVER a verb. That's the "golden rule" of prepositions.
Yesterday's New Morning Mercies (July 11) was filled with prepositions pointing to the ONE who is always the answer!
For to us a child is born, (Isaiah 9:6)
For from him and through him, and to him were all things. (Romans 11:36)
For by him, all things were created in heaven and on earth, visible and invisible, (Colossians 1:16)
And he is before all things and in him all things hold together. (Colossians 1:17)
...by your will (all things) existed and were created. (Revelation 4:11)
BTW, regardless of the preceding preposition....The answer is JESUS!
