We are not immune to drifting away from the gospel when we are not living our life fully for Christ, when we are holding on to a cherished sin or unable to release an idol in our lives. So many times, we in this great country of ours, are drawn into the seduction of materialism or the pursuit of pleasure and the avoidance of pain. These things often lead us to drift away from our Lord and Savior. Loads of our time is spent at work, pursuing pleasures, searching for self satisfaction - instead of communing with God in prayer, serving others and seeking His will for our lives by spending time in His word. We can resist this tendency to drift by taking the full responsibility for what we have heard about our Lord and Savior, by fully occupying ourselves with what we've heard, paying attention to or taking heed of these things we've heard. Jesus described drifting in the parable of the sower whereby His word either falls on soil that is too hard (a hardened heart), or rocky, shallow soil where the seed cannot take root (spiritually immature, fleshly minded - pursuit of pleasures & avoidance of pain is most important), or good soil yet full of weeds which choked out the seed (a church goer who loves God but is pre-occupied with earthly things).
