Here you will find the Poem Hymn 121 of poet Isaac Watts
Children devoted to God. [For those who practise infant Baptism.] Gen. 17:7,10; Acts 16:14,15,33. Thus saith the mercy of the Lord, "I'll be a God to thee; I'll bless thy num'rous race, and they Shall be a seed for me." Abram believed the promised grace, And gave his sons to God; But water seals the blessing now, That once was sealed with blood. Thus Lydia sanctified her house, When she received the word; Thus the believing jailer gave His household to the Lord. Thus later saints, eternal King! Thine ancient truth embrace; To thee their infant offspring bring, And humbly claim the grace.
