It's been said that a set of stairs has steps, a recipe has instructions, a school has grade levels, and the Christian life has 2 Peter 1:5-8.
Add to your faith virtue, then knowledge, then temperance, then patience, then godliness, then brotherly kindness, and then charity.
Each virtue builds on the previous one until the believer has reached spiritual maturity (not perfection). It isn't easy, but we will bear more fruit for The Lord's glory, and we will be blessed.
2 Peter 1:8 For if these things be in you and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ.
This is a call for believers to make a once-and-for-all decision to live for God no matter how difficult it might become.
