Why did God create us:-
Ephesians 1:5-6 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will,
6 To the praise of the glory of his grace, wherein he hath made us accepted in the beloved.
1. for the good pleasure of his will.
2. to the praise of the glory of his grace.
3. that we may be accepted in the beloved.
Revelation 4:11 Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created.
4. For his pleasure we were created.
Acts 17:24-25 God that made the world and all things therein, seeing that he is Lord of heaven and earth, dwelleth not in temples made with hands;
25 Neither is worshipped with men's hands, as though he needed any thing, seeing he giveth to all life, and breath, and all things;
Before Creation, we can only speculate. God is infinite. We are finite. But it does tell us that God has need of nothing. He doesn't need us. He doesn't need our praise and worship. He commands us to worship us for our own good, not his good. God doesn't need us nor our worship. If he needed anything he would not be God. Therefore he had no need to create anything. To speculate on what God did before Creation is needless speculation which the Bible commands that we should not do.
