Its not hard folks. Scripture says, "doers of the law are justified" Rom 2:13

Keeping the Law is the righteousness of Christ.

Romans 2:13
New International Version (NIV)¹³ For it is not those who hear the law who are righteous in God’s sight, but it is those who obey the law who will be declared righteous.

Romans 2:13
King James Version (KJV)¹³(For not the hearers of the law are just before God, but the doers of the law shall be justified.

Its not hard to understand:

1 John 5:3
American Standard Version (ASV)³ For this is the love of God, that we keep his commandments: and his commandments are not grievous.

How many Protestant Bibles must I quote. It's in your Bibles. Why do you deny the Word of God? 

Revelation 22:14
King James Version (KJV)¹⁴Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city. 

Revelation 22:14
English Standard Version (ESV)¹⁴ Blessed are those who wash their robes, so that they may have the right to the tree of life and that they may enter the city by the gates.

Sincerely,

De Maria
