<p>6:7 <i>Be not deceived</i>- The natural connection is with the warning in :3 to the self-righteous, self-congratulatory Judaists not to deceive themselves- by thinking that a few acts of legal obedience such as circumcision were the way to salvation. Paul here uses the same word the Lord often uses in warning that in the last days, the believers must be careful not to be deceived; as if Paul saw the collapse in Christ-centered faith as a sign of His return. John uses the same word about the deceivers who were seducing his converts to return to Judaism (1 Jn. 2:26; 3:7). The &quot;deceivers&quot; are described as being &quot;especially of the circumcision&quot; (Tit. 1:10). This warning not to be deceived is similar to the message of :1- that those with the Spirit should seek to restore those who had turned to Judaism, but considering themselves lest they also be tempted (see notes there).</p><p><i>God is not mocked</i>- To assume our obedience to commandment can save us is to mock God, connecting us with the Jews who mocked the Lord Jesus on the cross, at the very time He ended the Law and confirmed the new covenant of gracious salvation.</p><p><i>For whatever a man sows, that shall he also reap</i>- Knowing the terror of the Lord at the judgment, knowing that Christ will come, Paul sought to use this to persuade men, such as the believers at Corinth, to quit their sloppy attitude to God's Truth. Properly apprehending the reality of judgment to come makes us see the eye of the tiger, grasp the real issues of spiritual life, see the real essence of cross carrying Christianity. We will <i>believe</i> that whatever we sow, that we will reap; and we will therefore live accordingly. &quot;<i>That</i>&quot; shall he also reap is emphasized by the Greek. Those who trusted in works would reap what they had sowed- their few paltry works. Nothing more would be added; the Lord's all necessary righteousness would not be imputed to them, for they thought they didn't need it, like the man who entered the wedding without a provided garment.</p>
