Even after Christians are initially called and receive the Holy Spirit, it will take some time to FULLY grasp the NEED for us to want God and Jesus to COMPLETELY CONTROL us (as far as is possible while we are in this human form), and not merely influence us in a religious sort of way. For some of us, this can take a long time. Our goal even is to bring EVERY thought into the obedience of Christ (2 Corinthians 10:5).
God’s purpose for calling us is not just limited to having Christians be a ‘light’ in a dark world, but rather, the HIGHER purpose of having us being so COMPLETELY CONSUMED by His and Christ Jesus’ presence in us we are literally not our own anymore. Up to a point, Paul reached this stage as written in Galatians 2:20.
The problem is that some of us are satisfied with just the daily struggle of trying to be ‘good little girls and boys’ in a religious fashion; and too often, even this is motivated only by either (1) wanting to get ‘good stuff’ and blessings from our Father and Jesus (2) trying to merely ‘hang on’ until the Resurrection or (3) wanting to avoid Their wrath if we mess up. These attitudes can certainly lead to being “lukewarm” Christians and Revelation 3:16,17 clearly shows Their view on a “lukewarm” faith. A good article defining a lukewarm Christian is at http://chrismarlow.me/2008/06/are-you-a-lukewarm-christian/ .
Paul shows in 2 Timothy 1:6 that it is up to us to “stir up” or “rekindle” the “gift” that we have as Christians, if it becomes necessary. Other verses in the New Testament also clearly show that it is the individual Christian’s responsibility to develop an attitude in one’s heart to either “hunger and thirst after righteousness” (Matthew 5:6), become “lukewarm” in our faith (Revelation 3:16) or ultimately become like Demas who continued to “love this eon” (2 Timothy 4:10).
The Holy Spirit can urge as well as lead us but He will NEVER push, force or drag us.
All the best in Him,
