Not lagging in diligence, fervent in spirit, serving the Lord. Romans 12:11 (NKJV)
Like water cutting a channel through rock, spiritual erosion happens slowly but surely. Such decline happens so subtly that you are often unaware of its deadly work. It often comes through these almost imperceptible means:
A gradual shift from devotion to performance. Christ commended the church at Ephesus for their ceaseless labor but admonished them for neglecting their “first love” (Revelation 2:4 NASB). Spiritual attrition is inevitable when your passion for Christ becomes secondary to your deeds.
A gradual change from commitment to convenience. Faithfulness in little things is the stuff disciples are made of. When your relationship with Christ is structured to fit into your tidy agenda, spiritual decline sets in. Christ demands your all—both in season and out of season. you will not move on to spiritual maturity if you keep making excuses for why you cannot press on to know God.
A gradual change from repentance to tolerance of sin. As your love for and commitment to Christ wanes, it becomes easier to condone your sins instead of repenting of them. Such sins then establish strongholds in your life and frustrate your growth.
