Exodus reveals salvation as a journey from slavery to freedom, where God delivers His people by grace, not their own effort. Just as Israel was freed from Egypt, believers are freed from sin through Christ and called into a lifelong process of transformation. Faith in God, not works, brings redemption, while obedience, reliance on His Word, and the Holy Spirit sustain growth, strengthen believers, and lead them into lasting freedom, holiness, and deeper relationship with Him.
