"If you see your sinfulness, do not wait to make yourself better. How many there are who think they are not good enough to come to Christ. Do you expect to become better through your own efforts? “Can the Ethiopian change his skin, or the leopard his spots? then may ye also do good, that are accustomed to do evil.” Jeremiah 13:23 . There is help for us only in God. We must not wait for stronger persuasions, for better opportunities, or for holier tempers. We can do nothing of ourselves. We must come to Christ just as we are. SC 31.1"
"Can the Ethiopian change his skin, or the leopard his spots? then may ye also do good, that are accustomed to do evil."
Ellen White directly references Jeremiah 13:23 in this passage.
"But let none deceive themselves with the thought that God, in His great love and mercy, will yet save even the rejecters of His grace. The exceeding sinfulness of sin can be estimated only in the light of the cross. When men urge that God is too good to cast off the sinner, let them look to Calvary. It was because there was no other way in which man could be saved, because without this sacrifice it was impossible for the human race to escape from the defiling power of sin, and be restored to communion with holy beings,—impossible for them again to become partakers of spiritual life,—it was because of this that Christ took upon Himself the guilt of the disobedient and suffered in the sinner's stead. The love and suffering and death of the Son of God all testify to the terrible enormity of sin and declare that there is no escape from its power, no hope of the higher life, but through the submission of the soul to Christ. SC 31.2"
"For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,"
Both passages address the serious consequences of rejecting God's grace and the sacrifice of Christ. Hebrews 10:26 speaks of the lack of sacrifice for willful sin after knowing the truth, while EGW emphasizes that rejecting grace means rejecting the only way of salvation.
"For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord."
The EGW passage elaborates on the principle that sin leads to death, and salvation is only through Christ's sacrifice, which is the core message of Romans 6:23.
