The Lord Jesus has revealed that the way to Salvation is narrow and the way to Destruction is wide (Matthew 7:13-14). For a true Christian, regardless of the society he/she lives in, there is always a call to remain true to the precious teachings of the Bible, whether in good times or bad. In good times, in places where Christianity is widespread, one danger is compromising with the world in complacency. In such an environment, we can also find believers who darken the church doors occasionally but are not really converted. Unconverted believers are those who intellectually assent to the teachings of the Bible but have not surrendered their hearts to Jesus Christ.
Many are quick to claim salvation by grace (Ephesian 2:8-9), but are at a loss when confronted with the teachings of repentance (Mark 1:15; Acts 2:38; etc). It is very dangerous to make a theology out of one or two verses alone. Letting scripture interpret scripture is a sound way to go about it, and a fuller definition of salvation by grace is given by the same Paul in Titus 2:11-14. Upon careful examination of Paul's teachings we can easily conclude that repentance from sin and turning toward God in righteousness and holy living are clearly evident (Acts 20:21; 26:20; Romans 6:22-23... fruit to holiness). Jesus died on the cross to take away our sins --- not to allow us to indulge in sins and claim salvation.
