The following excerpts were taken from the The Pulpit Commentary (slightly revised in some places). The Scriptures are from the King James Bible.
“Man’s great need is a belief in God. Men believe in power, in wealth, in pleasure, in prosperity, in science. These things are prized, and therefore sought. Men believe that such things are desirable and attainable, and are worth toiling and suffering for. Yet these things cannot satisfy nor bless man’s inner need, for he has a spiritual and immortal nature, which earthly things cannot satisfy.”
“The thirst of the human soul is deep-seated in the nature of man. The powerlessness of the world to quench this thirst is an indication of the Divine origin of the soul. What the world cannot do, the Spirit of God can do. He can fill the soul with peace, purity, truth and power.”
“It is Jesus Christ who dispenses the satisfying gift of the Spirit. He said, ‘If any man thirst, let him come to me and drink’ (John 7:37). That faith is required from the thirsting soul is implied by the use of the words come and drink. This satisfying provision of the Spirit is offered freely, and must be appropriated by faith. ‘Whosoever will, let him take (by faith) the water of life freely.’ ” – Revelation 22:17
“There is an indispensable condition, without which no soul can come to Christ: Christ must first come to the soul. The Gospel must be preached, and must be received, for it is the Divine call of God, which alone can authorize the approach of sinful man to the Holy and Just One, Jesus Christ.”

AN INVITATION FROM JESUS: “Come unto me, all *ye that labor and are heavy laden, and I will give you rest” (Matthew 11:28). Forgiveness of sins, spiritual rest, and peace of mind, are found only in Jesus Christ.
THEREFORE: “Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon.” – Isaiah 55:7
* “ye” would be the same as “you” in the plural form
