Regularly gathering in the house of the Lord with brothers and sisters in Christ provides an "anchor" of support and accountability. But skipping church in order to pursue other interests is an obvious sign that a believer has begun to drift away from God. Less apparent are the men and women who mentally skip the worship service. The act of attending means nothing unless we make a deliberate decision to receive God's Word and apply it to our life. As the writer of Hebrews warned, if we do not pay attention to what we have heard, we will drift away from it (2:1).
However, Sunday morning is not the only time for receiving a steady diet of nourishing principles and encouragement from the Bible. We should be in its pages every day, reading and meditating for ourselves. When our interest in what God has to say decreases, we're already slipping out into troublesome waters. The only way to keep our way pure is by following His Word (Ps. 119:9).
If Bible reading is neglected, a prayer life has usually faded as well. Prayer is the way believers communicate with the Navigator. If we stop talking with Him, the God who once seemed so close soon feels far away. That chasm in our spirit is one more sign that we're far from shore and safety.
I've watched many a captain guide his cruise ship through a narrow channel. The crew members are intensely focused on their tasks because drifting means disaster. Life is full of narrow channels to navigate. We cannot afford to drift away from God and His Word. Only He can bring us safely through.
