Jesus did not propose or point out to us any new way to God's favor and eternal life, but on the contrary, he recommended that good old way which always was, and always will be the true way to life eternal; namely, keeping the commandments, or the loving God and our neighbor which is the same thing, and is the sum and substance of the moral law. (Matt. 19:17; 22:37-40)
This plain path-way to heaven lay neglected, and for the most part unfrequented; men both Jews and Gentiles having forsaken the fountain of living water, that is, the true way to life eternal; and shown to themselves cisterns - broken cisterns that can hold no water; that is, they had found out new and false ways of recommending themselves to God.
And this rendered our Savior's undertaking and ministry so much the more needful. And therefore it was truly said of him that he was to be not the maker, but the restorer, of right paths to dwell and walk in.
Jesus requires and recommends a conformity of mind and life to that unalterable rule of action which is founded in the reason of things as the only ground of divine acceptance, and as the only way to life eternal; so if men have lived in a violation of this righteous law by which they have rendered themselves displeasing to God, and worthy of His just resentment.
Secondly, Jesus requires and recommends repentance and reformation of their evil ways as the only ground of the divine mercy and forgiveness. The doctrine of repentance and remission of sin were what Jesus was chiefly concerned to announce to the world.
"Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven." (Matt. 18:3)
As to the doctrine that Jesus has, by his sufferings and death, made satisfaction to God for the sins of the world, and thereby merited the sinners discharge from condemnation, this doctrine Jesus did not preach, and therefore it cannot be any part of his Gospel, but it is directly opposite to it, and tends to subvert it.
The true doctrines of the Gospel of our Master and Savior Jesus Christ concerning this matter are the doctrines of repentance and remission of sins; that is, repentance and reformation is the only way to the divine mercy.
"For if you forgive others their trespasses," says Jesus, "your heavenly Father will also forgive you, but if you do not forgive others their trespasses, neither will your Father forgive your trespasses." (Matt. 6:14-15)
Let not therefore the sinner trust nor rely upon the vain words of men, but let them trust and rely upon the words of our Master, Jesus, who was sent by God to be their guide and instructor in this particular, and who, they may be assured upon good grounds, will not deceive them.
