You who are trying to be justified by law have been alienated from Christ; you have fallen away from grace. But by faith we eagerly await through the Spirit the righteousness for which we hope.
This verse says clearly, if you are trying to be justified by the law, you have fallen away from grace. if we fall away from grace, which is the free gift of God’s love and friendship, unearned by us, how then an we share it with others? Instead of serving them in love, we will expect then to “measure up” as we are doing. So, living in the freedom Christ provides through grace, means walking free in the friendship of God, making it possible to love others by serving them.
