And the priest will make atonement for the person who made a mistake by an unintentional sin before Jehovah, so as to make atonement for it, and it will be forgiven him.
~Numbers 15:28

Here we see Jehovah God’s merciful side, for he differentiates between one who sins out of ignorance or incompetence from one who sins as a consequence of pre-meditated evil.

Upon the realization of having committed a sin, Christians do not need to present an animal sacrifice as Israelites did, but Christ did give us instructions as to how to make amends with God.

“When you pray, go into your private room and, after shutting your door, pray to your Father who is in secret . . . ‘Our Father in the heavens, let your name be sanctified . . . and forgive us our debts, as we also have forgiven our debtors,’” (Matt. 6:6-12).

When sinning against someone, Christ instructed his followers to ‘first make your peace with your brother, and then, when you have come back, offer up your gift [to God]’ (Matt. 5:23,24).

If the sin is a serious wrongdoing, the congregation received these instructions:

“Is there anyone [spiritually] sick among you? Let him call the older men of the congregation to him, and let them pray over him, greasing him with oil in the name of Jehovah. And the prayer of faith will make the indisposed one well, and Jehovah will raise him up. Also, if he has committed sins, it will be forgiven him [by God]. Therefore openly confess your sins to one another and pray for one another, that you may get healed,” (Jas. 5:14-16).

The ‘greasing with oil’ figuratively refers to the refreshing Bible-based counsel mature elders give to the spiritually ‘indisposed.’

We should not, then,  fear admitting our sins, for Jehovah promises that he who is “leaving them will be shown mercy,” (Prov. 28:13).
