The devil is a better theologian than any of us and is a devil still.
'Let God be true but every man a liar' is the language of true faith.
In almost everything that touches our everyday life on earth, God is pleased when we're pleased. He wills that we be as free as birds to soar and sing our maker's praise without anxiety.
Refuse to be average. Let your heart soar as high as it will.
Salvation is from our side a choice, from the divine side it is a seizing upon, an apprehending, a conquest by the Most High God. Our 'accepting' and 'willing' are reactions rather than actions. The right of determination must always remain with God.
The Word of God well understood and religiously obeyed is the shortest route to spiritual perfection. And we must not select a few favorite passages to the exclusion of others. Nothing less than a whole Bible can make a whole Christian.
