William Williams (1717-1791) is a famous Welsh hymnwriter and this is one of his more popular hymns. It was sung by the congregation at the wedding of Prince William and Kate.
There are several versions of the hymn with verses added by others over time. One of my favorite renditions is by the group Indelible Grace (Chord Chart).
Below is the most common lyric for his hymn (some will swap Redeemer for Jehovah).
May He safely guide us on the journey to the other side. Amen.
Guide Me, O Thou Great Jehovah
Guide me, O thou great Jehovah,
Pilgrim through this barren land.
I am weak, but thou art mighty;
Hold me with thy powerful hand.
Bread of heaven, bread of heaven,
Feed me till I want no more;
Feed me till I want no more.
Open now the crystal fountain,
Whence the healing stream doth flow;
Let the fire and cloudy pillar,
Lead me all my journey through.
Strong deliverer, strong deliverer,
Be thou still my strength and shield;
Be thou still my strength and shield.
When I tread the verge of Jordan,
Bid my anxious fears subside;
Death of death, and hell’s destruction,
Land me safe on Canaan’s side.
Songs of praises, songs of praises,
I will ever give to thee;
I will ever give to thee.
