This is a lack of trust or confidence, either in ourselves or in someone else. Satan uses doubt to undermine the trust we have in God, yet the Bible states “You, O Lord, have not forsaken those who seek you” (Ps 9:10).
Insecurity is a fear that blocks advancement and change
the past or the fear of man hold you in bondage, rise up in faith and use the resources God has given to challenge wrong thought patterns. Some people feel insecure in their salvation because they must rely on faith. They would rather it was through some effort of good works or keeping of rules but scripture teaches that is both ineffective and impossible (Rom 3:20; Eph 2:8,9; 2 Tim 1:9). It is necessary to have an assurance of salvation to live effectively for Christ.
Insecure people can be manipulated by those with strong personalities. This is not meekness or submission but a weakness caused by a lack of assertion and so is a destructive force in their lives. We should be stable having a strong, firm faith in God, not continuously being unsettled by the experiences of life (Jas 1:6). Be firmly committed to God and His purposes.
Some people seek security in possessions – homes and money – but the Bible declares there is no lasting security in wealth (Mt 6:19-21; 1 Tim 6:17).
