You don't, not even if you are a Christian (which your pseudonym suggests you are not.)
Christians are to declare the good news about what Jesus Christ did to save sinners, by dying for their sins and being resurrected from the dead. They spread that good news all over the place, like an old-fashioned farmer sowing seed by hand. Whether that gospel seed will take root in hearts or not is dependent on the work of the Holy Spirit.
Christians are not out to promote a religion. They are out to promote the person of Jesus Christ, the living, glorious King of God's Kingdom. That is also the role of the Holy Spirit. Mere religiosity is worthless. It's not a religious system of doing A, then B then C in order to secure some kind of reward or merit from God that 'works'. It is only becoming convinced about the person of Jesus Christ that delivers people from mere religiosity.
