Mark 16:16-20

Mark 16:16 (KJB)
He that believeth and is baptized shall be saved; but he that believeth not shall be damned.

When a person come to belief in the Lord Jesus Christ and that belief is not just giving mental assent but it is the total commitment of the believer. A person not only believes but is also baptized shall be saved. The Lord gave two ordinances for the church to do, one is the Lord’s Supper and the other is water baptism. Water Baptism is not necessary for salvation because it is only an outward sign of what has already taken place internally because of salvation. (Eph 4:5 KJV) One Lord, one faith, one baptism, The baptism in view is being baptized into the Holy Spirit. (Mark 1:8 KJV) I indeed have baptized you with water: but he shall baptize you with the Holy Ghost. John’s baptism was one of repentance but when a person is baptized in the Holy Spirit, they are indwelled by Him for eternity and only those who are truly saved will have the Holy Spirit. Those who do not believe will be eternally damned. (John 3:18 KJV) He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.

Mark 16:17 (KJB)
And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;

Then Jesus gave some signs which will follow the ministry of the true believers. It was to confirm the ministry in the early church. The first sign was that devils will be cast out of those who were possessed. (Acts 16:18 KJV) And this did she many days. But Paul, being grieved, turned and said to the spirit, I command thee in the name of Jesus Christ to come out of her. And he came out the same hour. Then the second sign is that they will speak with new tongues. (Acts 2:7-8 KJV) And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilaeans? {8} And how hear we every man in our own tongue, wherein we were born? Since the gift of tongues had ceased, the new tongues that are spoken are the praises of God. (Isa 42:10 KJV) Sing unto the LORD a new song, and his praise from the end of the earth, ye that go down to the sea, and all that is therein; the isles, and the inhabitants thereof. When once our mouths spoke evil, they now speak the new song of the Gospel and the praises of God. In modern times, devils shall be cast out of people when a person becomes saved because the Holy Spirit will indwell the believer and that means the devil has to go.

Mark 16:18 (KJB)
They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.

Three other signs are given in this verse. The first is that one will be able to handle serpents and not be poisoned by them. (Acts 28:3-5 KJV) And when Paul had gathered a bundle of sticks, and laid them on the fire, there came a viper out of the heat, and fastened on his hand. {4} And when the barbarians saw the venomous beast hang on his hand, they said among themselves, No doubt this man is a murderer, whom, though he hath escaped the sea, yet vengeance suffereth not to live. {5} And he shook off the beast into the fire, and felt no harm. This is not giving license to handle poisonous snakes because if you get bit by one you will die from that bite. What is in view here is that God will protect His people even from the bite of a poisonous snake as He did with the Apostle Paul, if it is His will. It was a miraculous event and church history does record others who were in the same situation and did not die. The spiritual meaning is that a Christian will not be affected nor hurt by Satan who is also called the serpent. He was defeated by Christ and those that are in Christ are also victorious over him. (Rev 12:9 KJV) And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.

The next sign is that if one will drink something deadly, it will not hurt them. This is not a license to drink poison and expect God to negate the consequences. If one does that, they are in essence tempting the Lord God. (Mat 4:7 KJV) Jesus said unto him, It is written again, Thou shalt not tempt the Lord thy God. If someone accidentally drinks some poison and if it is God’s will they do not die, then they will not die at that point. It also has a spiritual meaning that if we are given a false Gospel which is deadly, it will not hurt us. (2 Cor 13:8 KJV) For we can do nothing against the truth, but for the truth. Truth can never be hurt by the false because truth is a constant state whereas falsity is always changing.

The last sign is that we lay hands on the sick and they will recover. This was done in the early church by Jesus and the apostles which confirmed their ministry was from God. (Acts 19:11-12 KJV) And God wrought special miracles by the hands of Paul: {12} So that from his body were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them.
Today we do not lay hands on the sick and see them recover. Some will recover from sickness by the means of our prayers matching God’s will for their life. When it talks about laying hands on, it is speaking of the giving of the Gospel to those who are spiritually weak or dead and they will revive in their spirits. (Acts 8:18 KJV) And when Simon saw that through laying on of the apostles' hands the Holy Ghost was given, he offered them money, Laying on of hands is symbolic of giving the Gospel.

Mark 16:19 (KJB)
So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God.

Once the Lord had finished speaking to them on the Mount of Olives. He was then taken up and received into Heaven as He ascended to sit on the right hand of God the Father which He had told His disciples that He was going to do. (Acts 1:8 KJV) But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. The disciples were to wait in Jerusalem until they received the promise of God which was the Holy Spirit who would empower their ministries.

Mark 16:20 (KJB)
And they went forth, and preached every where, the Lord working with them, and confirming the word with signs following. Amen.

After they had received the Holy Spirit, they were now empowered to begin to fulfill the Great Commission and they went and preaching the Gospel wherever they went. The Lord had also confirmed their ministries by working miracles in concert with the preaching of the Gospel. The Gospel of Mark being a completed book is still being acted out today with the Gospel going to every part of the world and will until the last day.

The word “Amen” is very familiar to the Christian because we end our prayers with it. The word means ”truly, surely, so let it be, indeed.” It is also at the end of all four gospels which means God is giving each Gospel His commendation that each one is truth. The word in the Greek for Amen is also used many times in the Gospels as “verily.” (John 3:3 KJV) Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.  We understand “verily” to mean “in truth, in fact, or certainty.” It is also a word of affirmation. So the word “amen” at the end of the Gospel of Mark is also an important word because it is stating that the Gospel of Mark is ending at verse 20 and the contents of it are true, fact, and of a certainty.
