Isaiah 55:6
ESV - 6 Seek the Lord while he may be found; call upon him while he is near.
Is.55.6 suggests a time when men cannot find God. The Bible mentions six of these times: 1. When they turn their hearts away from Him and will not hear (Dt 30:17-18 1 Sam 28:6; Chr. 10:13-14 Ps 95:7-11 Jer 11:10-12 Mt 13:13-15). 2. When they mock God and scorn at His dealings until calamity comes (Prov 1:23-31). 3. When they become too proud and stubborn to humble themselves before Him (Num 16). 4. When they neglect to settle all matters with Him until judgment falls (Acts 5:1-11). 5. When they die in sin (Heb 9:27). 6. When they blaspheme the Holy Spirit (Mt 12:31-32).
