Misc Praise Songs - Seek Ye First chords

I don't know what is with all those minor chords but I figured this out on my own and 
sounds decent
[ Tab from: http://www.guitaretab.com/m/misc-praise-songs/293319.html ]
C       G         F          C
Seek ye first the Kingdom of God
F       C       G    G7
And His righteousness
C             G               F          C
And all these things shall be added unto you
F    C        G C
Hallelu, Hallelujah!

Follow the same pattern through out the whole song
