1st Samuel 20:3 And David swore moreover, and said, Thy father certainly knows that I have found grace in thine eyes; and he saith, Let not Jonathan know this, lest he be grieved: but truly as the Lord lives, and as thy soul lives, there is but a step between me and death.
In fact, the same writer goes on to speak of some of his own experiences in which he seemed to be living on the edge for a while, having to look er his shoulders constantly. Thus, even though David leaned upon the promises of deliverances, and even though he expected the blessing, he did not presume to think that in every single instance, this would be the case, and that he would have smooth sailing in every situation.
Therefore, we should pay very close attention to the following. First of all, God can do anything except lie and He is not restricted to what we often see as the only options on the table. God has a thousand ways of doing the very same thing. In other words, if He has promised to heal you, He is not limited, nor restricted to conventional ways and means. He can touch you, He can speak the healing.
He can use clay, He can use spit, He can use a rod He could use a tree, He could use a doctor, a nurse, an Elder, a Pastor, or a layman. And yet, God is not limited or restricted to any or all of the above, for He can just think the blessing into reality, and a person will receive it. Therefore, the outlook, and perspective of the Christian, as far as expecting a blessing is concerned, is to always leave the door wide open, because you never know what God will do.
Matthew 8:5 And when Jesus was entered into Capernaum, there came unto him a centurion, beseeching him, 6 And saying, Lord, my servant lieth at home sick of the palsy, grievously tormented. 7 And Jesus saith unto him, I will come and heal him.
May The Lord add His blessing to the study of His word. God bless!
