The following may be of some help on the above link.

(C)Eternal Father (F) strong to (C)save, whose arm hath bound the (G)rest(D)less (G)wave.

who (G7)bids the (C)mighty (A7)ocean (D)deep (B7)its (Em)own appointed (B7)limits (Em)keep

The way the chords are written seem o.k. for the remainder of the lyrics ~ the only problem is that the (B7) is shown a bit late .in the second, third, and forth verse .
Example   2nd verse   "....(B7)Wher(Em)ever
3rd verse...... (B7)save (Em)all...
4th verse   ...... (B7)pro(Em)tect.....
