Step 9 - We made direct amends to such people whenever possible, except when to do so would injure them or others

Mat 5:9  Blessed are the peacemakers: for they shall be called the children of God. 

Jesus is telling us that when we are makers of peace, that we become truly children of God.The eighth and ninth steps are about making peace with those whom we have wronged, as much as is within us to do. The usual practice is to sweep wrongs of the past under the rug and try to forget about them. But by making appropriate amends, we are able to go the second mile and oftentimes bring peace and goodness where there might have been lingering doubts or mistrust or confusion before. We can become peacemakers who are blessed as children of God. 

 Mat 5:23  Therefore if you bring your gift to the altar, and there remember that your brother has anything against you; 
Mat 5:24  Leave there your gift before the altar, and go your way; first be reconciled to your brother, and then come and offer your gift. 

We are told in clear terms here that we are to be reconciled with our brother if they have things against us. This means not only are we to be diligent in trying to make things right when there is resentment against us, but it also implies that we should be sensitive to the thoughts and feelings of others so that we can know if there is any lingering resentment or anger toward us. There could also be an implication that since they are a brother or sister in the Lord, then they will be reasonable and sensitive to God's leading so that when we sincerely try to be reconciled, that there will be true reconciliation. 

Mat 5:25  Agree with your adversary quickly, while you are in the way with him; lest at any time the adversary deliver you to the judge, and the judge deliver you to the officer, and you be cast into prison. 
Mat 5:26  Verily I say unto you, you shall by no means come out of there, till you have paid the last penny. 

This may be the corollary of the previous two verses for how to deal with the resentment of others, but this time they are for our adversaries, those who are truly set against us and may not be in the family of God. Here we are to be very careful to not offend if possible, knowing that the consequences could be severe. And by agreeing that we have done wrong, that we were remiss or negligent in our dealings with them, can often be all that it takes to make their anger and resentment subside to something that is manageable.
