Feel unworthy to draw near to the Lord? Martin Luther said this back in 1521 in a letter to his friend Melanchthon:

God does not save those who are only imaginary sinners.

Be a sinner, and let your sins be strong; but let your trust in Christ be stronger, and rejoice in Christ who is the victor over sin . . . the Lamb who takes away the sin of the world.

No sin can separate us from Him, even if we were to kill or commit adultery thousands of times each day. Do you think such an exalted Lamb paid merely a small price with a meager sacrifice for our sins?
