A full and hearty choosing of this God for our God and portion, in opposition to all other persons and things : Psalm 16:2. ‘my soul, thou hast said unto the Lord, Thou art my Lord.’ Psalm 119:57. ‘Thou art my portion, Lord.’ We are not at liberty to choose our God or our portion, what we will give our hearts to, love most, &c. God, as our great Lord and Master, has determined that for himself. And law vengeance will pursue the neglect of it.
