"And Jesus, moved with compassion, put forth his hand, and touched him, and saith unto him, I will; be thou clean." (Mark 1:41)

When the Lord Jesus makes a promise, that promise is sure to be fulfilled. When He made the above promise to the leper, "immediately the leprosy departed from him" (Mark 1:42). The promise may not always be carried out as rapidly as this, but it will come.

Look at some of the wonderful "I will's" of Christ. "Follow me, and I will make you fishers of men" (Matthew 4:19) is His promise to all His true disciples (that is, those who follow Him). But first they must come to Him, and to those who come He promises, "Him that cometh to me I will in no wise cast out"
(John 6:37).

Another gracious promise to all who come: "Come unto me, all ye that labour and are heavy laden, and I will give you rest" (Matthew 11:28). He also promises special love to those who obey Him. "He that hath my commandments, and keepeth them, . . . shall be loved of my Father, and I will love him, and will manifest myself to him" (John 14:21).

There is a tremendous promise in John 14:13: "And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son." He even emphasized it in the next verse: "If ye shall ask any thing in my name, I will do it" (John 14:14).

He has also promised to come back again, and we can be certain He will do as He said: "And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also" (John 14:3). But probably the greatest of all His promises was given in His intercessory prayer. "Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory" (John 17:24). HMM
