"God has called us to live holy lives" (1 Thessalonians 4:7), but it's easy to stray if our devotion is less than wholehearted:
"I seek you with all my heart; do not let me stray from your commands." Psalm 119:10
It's usually a gradual move, a slow change in one's perspective, a continual giving of one's heart to "other gods."
Some methods of evangelism attract people to the Gospel by promising peace, joy, love, hope, and purpose and never explaining the cost of following Christ (Luke 14:27-33).
Perhaps that's why our present Christian culture often overlooks and excuses weak faith and back-sliding.
Let's make sure that we never lower God's standards to suit our lifestyle. Instead, let's judge our goals, values, and "treasures" with Scripture.
