"But God" ... What a wonderful phrase ... what a wonderful truth.
I do not recall the passage the poster was referring to (if he had actually stated it or not), but the phrase and his comment stuck with me. But God... So I started looking through the Bible to see some passages where this phrase (as well as "But the Lord") is used. Here are some that particularly blessed me:
Genesis 39:20-21 And Joseph's master took him, and put him into the prison, a place where the king's prisoners were bound: and he was there in the prison. But the LORD was with Joseph, and shewed him mercy, and gave him favour in the sight of the keeper of the prison.

But the LORD thy God shall deliver them unto thee, and shall destroy them with a mighty destruction, until they be destroyed.
Deuteronomy 23:4-5 Because they met you not with bread and with water in the way, when ye came forth out of Egypt; and because they hired against thee Balaam the son of Beor of Pethor of Mesopotamia, to curse thee. Nevertheless the LORD thy God would not hearken unto Balaam; but the LORD thy God turned the curse into a blessing unto thee, because the LORD thy God loved thee.
Judges 15:18-19 And he was sore athirst, and called on the LORD, and said, Thou hast given this great deliverance into the hand of thy servant: and now shall I die for thirst, and fall into the hand of the uncircumcised?

But the LORD is with me as a mighty terrible one: therefore my persecutors shall stumble, and they shall not prevail: they shall be greatly ashamed; for they shall not prosper: their everlasting confusion shall never be forgotten.

For me, I would have to say the references to God being with Joseph, the passage about Jesus rising from the dead, the part about God being the strength of my heart, that the Lord has quickened me together with Christ, and that He has revealed through His Spirit the things that He hath prepared for us.
