Enter ye in at the strait gate. . . because strait is the gate, and narrow is the way, which leadeth unto life.
Men have always come up with various ways to get in favor with God and thus eventually, hopefully, be in heaven. But the Bible teaches plainly that the way to have eternal life in heaven and a full life on earth is through the strait gate, which is Christ. Without Him we cannot possibly get to heaven or find favor with God. Enter in at the strait gate and walk the happy path to heaven.
