John Wesley on the Kingdom of Heaven

Therefore strive now, in this your day, to “enter in at the straight gate” [seek to get into heaven]. Here is a short, a plain, an infallible rule, before you enter into particulars. In whatever profession you are engaged, you must be [single minded and purposeful], or be damned! The way to hell has nothing singular in it; but the way to heave is singularity all over. If you move but one step toward God, you are not as others are. But [don’t let that bother you]. It is far better to stand alone, than to fall into the pit.
