He takes the best and the wisest course under heaven to preserve his good name in the world and to maintain the peace of his conscience, who is most studious and industrious to abstain from all appearances of evil (1Th 5:22).

Again, A GOOD CONSCIENCE is another spring of assurance: 2 Cor 1:12, "For our rejoicing is this—Our conscience testifies that we have conducted ourselves in the world, and especially in our relations with you, in the holiness and sincerity that are from God. We have done so not according to worldly wisdom but according to God's grace." So 1 John 3:21, "Beloved, if our heart condemns us not, then have we confidence towards God." A good conscience has sure confidence; he who has it sits, Noah-like, in the midst of all disruptions and turmoils, in sincerity and serenity, uprightness and boldness. A good conscience and a good confidence go together.

Heaven on earth, Chapter 1

The precious jewel of faith can be held in no other place - but in a pure conscience; which is the only royal palace wherein it must and will dwell: 1 Tim, 1:19, "Holding faith and a good conscience:" Heb. 10:22, "Let us draw near with a true heart, in full assurance of faith, having our hearts sprinkled from an evil conscience." He who comes to God with a true, honest, upright heart, being sprinkled from an evil conscience, may draw near to God in full assurance of faith. Whereas guilt clouds, clogs, and distracts the soul, that it can never be with God, either as it would or as it should. A good conscience has sure confidence. Conscience is a thousand witnesses for or against a man. Conscience is God's preacher in the bosom. It is better, with Evagrius, to lie secure on a bed of straw - than to have a turbulent conscience on a bed of down. It was a divine saying of Seneca, a heathen, namely, "That if there were no God to punish him, no devil to torment him, no hell to burn him, no man to see him - yet would he not sin, for the ugliness of sin, and the grief of his own conscience."

 

... Twenty-fourthly, One sin allowed and lived in, will eat out all peace of conscience. As one jarring string will spoil the sweetest music; so one sin countenanced and lived in will spoil the music of conscience. One pirate may rob a man of all he has in this world.

 

The Golden Key to open hidden treasures

Quest. But what course must we take? What means must we use, to find out that 'particular sin', for which God corrects us, or which hath brought the rod upon us?

Ans. 1. Observe what that sin is, that thy conscience doth most upbraid thee with, and check thee for. Conscience is God's preacher in the bosom, Gen. xlii. 21, 1. 15-17. Now, observe what that particular sin is, that conscience doth most smartly and roundly correct and chastise thee for; for it is ten to one but that is the sin that hath brought the rod upon thee. The voice of conscience, and the voice of the rod, do usually echo one to another. It is very rare to find a difference between the language of conscience and the language of the rod. Conscience is God's deputy, God's spy, God's notary, God's viceroy; and therefore do not despise the voice of conscience, do not turn off conscience, as Felix "turned off" Paul, Acts xxiv. 25. If the secret cry of conscience be, Oh, this is for thy pride, or this is for thy passion, or this is for thy self-love, or this is for thy earthliness, or this is for thy carnalness, or this is for thy hypocrisy, or this is for thy formality, etc., it will be your wisdom to apply to the secret cry of conscience.
...  Neglect of duty will never get guilt off the conscience. ...
