Thomas Boston (Works, vol. 10, p. 495):
Seek Christ in ordinances, and come to them with a design to find Christ there. When ye go to read the word, to secret duties, or family duties, or public ordinances, think with yourselves, 'I am going to wisdom’s gates, O shall I not see the King’s face? find the smell of his garments, get some communion with Christ?' When Mary missed him in his grave, she could not be satisfied with a vision of angels, but wept on, till she found him, John 20:11–16.... He is well worth the seeking. 'He that findeth Christ, findeth life.' If his transcendent beauty and peerless excellencies were known, we could not but seek him till we had found him; John 4:10, 'If thou knewest the gift of God,' says Christ to the woman of Samaria, 'and who it is that saith to thee, Give me to drink; thou wouldst have asked of him, and he would have given thee living water.' They that find him are made up for time an eternity. When ye come to ordinances, know ye where ye are? Ye are upon a beautiful field, and it may be your own. Ye see the surface of it, but know ye what is in the bowels of it? A treasure, and Christ is that treasure, Matth. 13:44. The ordinances are the earthen vessels, but there is a treasure in them, 2 Cor. 4:7.
