Why we Christians still have to struggle with sins?

[Mercy Shown]

Yeah...it's looks like you are stuck on Roman Christianity Doctrine and you are bringing destruction to yourself whether you understand this or not. In, (Is. 42:21) we find another prophecy concerning Christ and the law. It reads, (v.21) The LORD is well pleased for his righteousness' sake; he (Jesus) will magnify the law, and make it honourable. When you magnify something you enlarge it and bring it out more of its detail and richness. Jesus revealed the fulfillment of this prophecy when he explained, (Mat.5:27-28) (v.27) Ye have heard that it was said by them of old time, Thou shalt not commit adultery: (v.28) But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart

By magnifying the law and making it honorable, the spiritual intent of the law is now emphasized which goes far beyond the mere the physical intent. God has raised His standards, not lowered them! All God ever wanted was what was best for us! He designed us to be His children. We are happiest when we love and obey Him. He is a God who is totally righteous and holy. God cannot sin. And He wants us to follow in His footsteps. The person that says, (1John:2:6) “that saith he abideth in him ought himself also so to walk, even as he walked.”

Jesus says in (Mat.5:17-19) (v.17) Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. (v.18) For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. (v.19) Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.

Jesus came to fulfill, to fill to the full (Gk. plereo). He fulfilled many prophecies - but not all. There are many in the Book of Revelation still to be fulfilled. There is still some in the Old Testament that hasn’t been fulfilled. Jesus at His first coming came to fulfilled that which was written for Him to fulfill at His first coming. He has NOT fulfilled everything that was written for Him to do. And He kept all of the Law that he could - but that was not all! He was not a Temple priest. He was not a woman. He could not keep the laws intended only for priests and women. No matter how you think about Jesus, there is still much to be fulfilled! So not even the smallest part has yet passed from God's Law!

Jesus made it quite clear that anyone who would break even the least commandment and teach people to do so would be called the least in the kingdom of heaven. The fact is, God did not find fault with His laws but rather with the people who did not obey them. (Heb.8:7-8) (v.7) For if that first covenant had been faultless, then should no place have been sought for the second.(v.8) For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah: The writer of Hebrews then proceeds to quote Jeremiah 31:31-34, quoted above. Under the New Covenant we now have a living High Priest, Jesus Christ, who can make intercession for us. One who was tempted in all things as we are, yet without sin. He is an intercessor who understands our weaknesses because He lived as a human being.

Claim 2: The Law cannot pass until heaven and earth pass.​

Response:
Jesus did not say the Law would never pass.
He said it would not pass “until all is fulfilled.”

Matthew 5:18

“…till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.”

And what did Jesus do?
He fulfilled it — completely.

Luke 24:44

“All things must be fulfilled which were written in the law of Moses, and in the prophets, and in the psalms, concerning me.”

Romans 10:4

“For Christ is the end of the law for righteousness to everyone that believeth.”

The Law stood until its purpose was accomplished in Christ — to reveal sin and point to Him.
When the reality (Christ) came, the shadow (Law) was fulfilled (Colossians 2:16–17).

Claim 3: Jesus has not fulfilled everything, so the Law still stands.​

Response: This confuses prophecy fulfillment (some yet to come) with Law fulfillment (already completed).
The Law and the Prophets are different categories — both foretold things, but the Law’s requirements were fully met in Christ’s life, death, and resurrection.

Hebrews 10:9–10

“He taketh away the first, that he may establish the second.
By the which will we are sanctified through the offering of the body of Jesus Christ once for all.”

The “first” — the system of law and sacrifice — was taken away because its purpose was completed in Christ.

Claim 4: The Law wasn’t at fault, the people were — therefore the Law remains.​

Response:
Hebrews 8:7–13 does say the fault was with the people, but the conclusion is that the old covenant was made obsolete and replaced with a new one.

Hebrews 8:13

“In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.”

The new covenant doesn’t patch up the old system; it replaces it with a better one based on Christ’s blood (Luke 22:20).

The Law wasn’t evil — it was holy (Romans 7:12).
But it could not give life (Galatians 3:21), so God gave a new covenant where the law is written on the heart, not engraved on stone (Jeremiah 31:33; 2 Corinthians 3:3).

Claim 5: Whoever breaks even the least commandment is least in the kingdom.​

Response:
This warning was given to those who thought they could enter the kingdom through law-keeping.
Jesus was contrasting self-righteousness with kingdom righteousness that comes only through Him.

Matthew 5:20

“Unless your righteousness exceeds the righteousness of the scribes and Pharisees, you will never enter the kingdom of heaven.”

How can anyone’s righteousness exceed the Pharisees’?
Only by receiving Christ’s righteousness by faith.

Philippians 3:9

“…not having mine own righteousness, which is of the law, but that which is through the faith of Christ…”

Those who teach justification by the Law are the ones breaking it, because they reject the very purpose of the Law — to drive us to Christ (Galatians 3:24–25).
