Sin claims to free but in fact it kills.

Too often preachers want to deal with people simply at the level of publicly accessible reason. We participate with them in their own epistemology. But this is not New Testament preaching. We have a message that is not from this world; it is from God. We don't know it by our own cleverness; we know it because God has revealed it.

Membership is the church's corporate endorsement of a person's salvation.

There is simply so much reason to believe the good news of Jesus Christ in history, in Scripture, as well as in our own experience that it would take a leap of faith not to believe in the gospel.

Actually, having a few questions of your own shouldn't prevent you from sharing the gospel with others. You can explain to them that while you still have a few unresolved questions yourself, you don't have enough faith to not believe.

According to the New Testament, the church is primarily a body of people who profess and give evidence that they have been saved by God's grace alone, for His glory alone, through faith alone, in Christ alone.

There are opportunities around. It takes time and motivation to take them.
