If we do not abide in prayer, we will abide in temptation. Let this be one aspect of our daily intercession: "God, preserve my soul, and keep my heart and all its ways so that I will not be entangled." When this is true in our lives, a passing temptation will not overcome us. We will remain free while others lie in bondage.
To believe that He will preserve us is, indeed, a means of preservation. God will certainly preserve us, and make a way of escape for us out of the temptation, should we fall. We are to pray for what God has already promised. Our requests are to be regulated by His promises and commands. Faith embraces the promises and so finds relief.
Our great Pattern hath showed us what our deportment ought to be in all suggestions and temptations. When the devil showed Him "all the kingdoms of the world and the glory of them," to tempt Him withal, He did not stand and look upon them, viewing their glory, and pondering their empire.... but instantly, without stay, He cries, "Get thee hence, Satan." Meet thy temptation in its entrance with thoughts of faith concerning Christ on the cross; this will make it sink before thee. Entertain no parley, no dispute with it, if thou wouldst not enter into it.
Without absolutes revealed from without by God Himself, we are left rudderless in a sea of conflicting ideas about manners, justice and right and wrong, issuing from a multitude of self-opinionated thinkers.
