No heart can conceive that treasury of mercies which lies in this one privilege, in having liberty and ability to approach unto God at all times, according to his mind and will.
This quote from the Puritan John Owen was mentioned in his work The Discourse of the Work of the Holy Spirit in Prayer. In the context of this work Owen follows with:
It is a matter of praise and glory to God, in an especial manner, that He hath granted an amplification of this privilege under the gospel. The spirit is now poured forth from above, and enlarged in His dispensation both intensively and extensively.
Which is to say that we, as believers, should not take lightly this treasure and resource from the Lord. To even imagine the wealth of wisdom and grace would be a fruitless effort on our part. In preaching to myself I would have to ask, what prevents me from participating in this freedom and going to the throne of grace? It is only sin that prevents me. My old nature. By God’s grace alone I shed this old man and seek after His mind and His will.
