Inconsistent Logic?

Just wondering:

1) If I truly believe God is completely sovereign.
2) If I truly believe he alone authors life.
3) If I truly believe His word is without error.
4) If I truly believe He is NEVER mistaken
5) If I truly believe He only does that which glorifies His name.
6) If I truly believe I am a living sacrifice to Him.
7) If I truly believe in His Kingdom on earth.
8) If I truly believe that I am part of a spiritual army.
9) If I truly believe I am a living sacrifice to Him.
10) If I truly believe I am not my own, but have been bought at the ultimate price.
11) If I truly believe abundant life and joy are found in keeping His commandments.
12) If I truly believe that his grace is sufficient.
13) If I truly believe children are a blessing from the Lord.
14) If I truly believe God was not making a mistake when he repeatedly says He
opens and closes wombs.
15) If I truly believe that children are arrows in the hands of a warrior...

How can I consistently defend attempting to control the number of children God sends me? Shouldn't my struggle be against the kingdom of this world...against my flesh...rather than against the will of the all loving, all compassionate, all knowing Sovereign Life-giver?
