Galatians is an important letter because it speaks clearly about the grace and salvation. People have told the believers in Galatia that they need to follow the Mosaic Law in order to be acceptable to God. God has already done the work of salvation and given it to us as a gift. A gospel of grace means that Jesus alone makes us acceptable to God; the religious law has no bearing on whether we are acceptable to God.
It isn’t following the rules that matters, but faith expressed through love. Faith expressed through love isn’t about obligation or earning a way to heaven, rather heartfelt gratitude. It is the work of the Spirit. If freedom is living without the worry of control or coercion, we are truly free because God has already undone all the barriers between God and humanity.
