Who is it who leads us in “way everlasting?” Is it ourselves? I think not. Instead, our prayer is that God Himself should “search [us], know [our] hearts, try [us] and know [our] thoughts.” Then, once He discovers those ways in us which are “grievous,” He should “lead [us]” out of them and into His pasture, His way.
Jesus says, “I Am the way, the truth, and the life.”
And He promises that anyone who comes to Him will never thirst again.
