Absolutely!
In John 6:28-29 He was asked point blank “works we must do” for God.
Our King’s response is genius and speaks volumes about works-based salvation theory. He had the opportunity to deliver an hour long lecture on what must be done, but He didn’t.
John 6:28-29
28 Then they said to Him, “What shall we do, that we may work the works of God?”
29 Jesus answered and said to them, “This is the work of God, that you believe in Him whom He sent.”
The only cure for the sin disease is accepting Christ’s 100% free gift of salvation by his sacrifice on the cross for the propitiation of our sins.
Believe in Him as Savior, Believe that the Father raised Him from the dead on the 3rd Day, and call our to Jesus - all stated plainly in Romans 10:9-13.
If you read further, Jesus is talking about the Eucharist,read it all in context:
[26] Jesus answered them, and said: Amen, amen I say to you, you seek me, not because you have seen miracles, but because you did eat of the loaves, and were filled. [27] Labour not for the meat which perisheth, but for that which endureth unto life everlasting, which the Son of man will give you. For him hath God, the Father, sealed. [28] They said therefore unto him: What shall we do, that we may work the works of God? [29] Jesus answered, and said to them: This is the work of God, that you believe in him whom he hath sent. [30] They said therefore to him: What sign therefore dost thou shew, that we may see, and may believe thee? What dost thou work?
[31] Our fathers did eat manna in the desert, as it is written: He gave them bread from heaven to eat. [32] Then Jesus said to them: Amen, amen I say to you; Moses gave you not bread from heaven, but my Father giveth you the true bread from heaven. [33] For the bread of God is that which cometh down from heaven, and giveth life to the world. [34] They said therefore unto him: Lord, give us always this bread. [35] And Jesus said to them: I am the bread of life: he that cometh to me shall not hunger: and he that believeth in me shall never thirst.
[36] But I said unto you, that you also have seen me, and you believe not. [37] All that the Father giveth to me shall come to me; and him that cometh to me, I will not cast out. [38] Because I came down from heaven, not to do my own will, but the will of him that sent me. [39] Now this is the will of the Father who sent me: that of all that he hath given me, I should lose nothing; but should raise it up again in the last day. [40] And this is the will of my Father that sent me: that every one who seeth the Son, and believeth in him, may have life everlasting, and I will raise him up in the last day.
[41] The Jews therefore murmured at him, because he had said: I am the living bread which came down from heaven. [42] And they said: Is not this Jesus, the son of Joseph, whose father and mother we know? How then saith he, I came down from heaven? [43] Jesus therefore answered, and said to them: Murmur not among yourselves. [44] No man can come to me, except the Father, who hath sent me, draw him; and I will raise him up in the last day. [45] It is written in the prophets: And they shall all be taught of God. Every one that hath heard of the Father, and hath learned, cometh to me.
[44] “Draw him”: Not by compulsion, nor by laying the free will under any necessity, but by the strong and sweet motions of his heavenly grace.
[46] Not that any man hath seen the Father; but he who is of God, he hath seen the Father. [47] Amen, amen I say unto you: He that believeth in me, hath everlasting life. [48] I am the bread of life. [49] Your fathers did eat manna in the desert, and are dead. [50] This is the bread which cometh down from heaven; that if any man eat of it, he may not die.
[51] I am the living bread which came down from heaven. [52] If any man eat of this bread, he shall live for ever; and the bread that I will give, is my flesh, for the life of the world. [53] The Jews therefore strove among themselves, saying: How can this man give us his flesh to eat? [54] Then Jesus said to them: Amen, amen I say unto you: Except you eat the flesh of the Son of man, and drink his blood, you shall not have life in you. [55] He that eateth my flesh, and drinketh my blood, hath everlasting life: and I will raise him up in the last day.
"And why call ye me, Lord, Lord, and do not the things which I say?" (Lk. 6:46 AV).
Just believing that He exits will not get you to salvation. What is saving is knowing that after you have received the gift of eternal life, your good works will then please God, prove it, and glorify God.
