Galatians 6:7, 9, 15

Do not be deceived, God is not mocked [He will not allow Himself to be ridiculed, nor treated with contempt nor allow His precepts to be scornfully set aside]; for whatever a man sows, this and this only is what he will reap.

Let us not grow weary or become discouraged in doing good, for at the proper time we will reap, if we do not give in.

For neither is circumcision anything [of any importance], nor uncircumcision, but [only] a new creation [which is the result of a new birth—a spiritual transformation—a new nature in Christ Jesus].
