The law {the 10 commandments} does not lead us in circles. But it does show our relationship to God.
MATT.7 [22] Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?[23] And then will I profess unto them, I NEVER KNEW YOU: DEPART FROM ME, YE THAT WORK INIQUITY.
PSALMS 119 [113] I hate vain thoughts: but thy law do I love.[114] Thou art my hiding place and my shield: I hope in thy word.[115] DEPART FROM ME, YE EVILDOERS: FOR I WILL KEEP THE COMMANDMENTS OF MY GOD.[116] Uphold me according unto thy word, that I may live: and let me not be ashamed of my hope.
Depart from me! Seems there will be many people who will be saying I believe when Jesus returns. Who had talked of Jesus and spoke in his name. Some that even have cast out devils in the name of Jesus. But in that day Jesus will say to the many, depart from me...I never knew you.
1JOHN2 [3] AND HEREBY WE DO KNOW THAT WE KNOW HIM, IF WE KEEP HIS COMMANDMENTS.[4] He that saith, i know him, and keepeth not his commandments, is a liar, and the truth is not in him.[5] But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.
Theres the people who know God and will given the free gift. They that observe to keep Gods 10 commandments. Read the 4th. Remember....
TITUS 1 [13] This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith; [14] Not giving heed to Jewish fables, AND COMMANDMENTS OF MEN, that turn from the truth. [15] Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled. [16] THEY PROFESS THAT THEY KNOW GOD; BUT IN WORKS THEY DENY HIM, being abominable, AND DISOBEDIENT, and unto every good work reprobate.
In Titus you will find people that profess they know God (they say they believe) but in works they deny Him. They do not know God.
