We are not bound by fear of punishment or obligation to obey but we have the freedom to choose to follow God out of love for Him.  He enables us to become more like Him by the power of His Spirit.

2 Cor 3:17  Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. ¹⁸ And we all, who with unveiled faces contemplate the Lord’s glory, are being transformed into his image with ever-increasing glory, which comes from the Lord, who is the Spirit.
