Not really. Christians come in all shapes.
some people go to church on Easter and Christmas then call themselves Christians. If they don't live the faith, they are what is referred to in the Bible as chaff. The wheat...the ones who live day-to-day according to Christs teachings they best they can are true Christians....followers (imitators in church and out of church) of Christ. Not that we don't sin....we do. But there is genuine sorrow afterward and an attempt, with God's help, to do better next time.
True Christians will look to follow God's leading and not mislead to achieve positions of influence. And hopefully the power would not corrupt if it is achieved...but in many cases even good and wise people (like David and Solomon) became corrupt....but finally did repent.
Bottom line is christians wear thier heart on thier sleeve and should have no motivation to lie...but they are not perfect either.
