Of course a believer in Christ doesn't abandon and forsake His commandments....
Does that mean all who know Him uphold them perfectly? No.
We understand and value them and keep them.
What do you mean faith in who?
Of course Jesus is the only way.
The only door to heaven.
Not our walk, not our works, not the number of fruit He produces in us.
Some trees will have less than others, but they are equally saved by our Lord and savior Jesus.
We ENTER IN Jesus who is the WAY (that we should WALK), the TRUTH (that we should believe) and the LIFE (that we should ENTER and live).
Did He say that we can ENTER without obeying His commands or being deliberately DISOBEDIENT? Did he teach obedience to God and instruct His disciples to teach it as well unto all nations and promised to be with them and in them with the Father?
NIV1984 Matthew 19:16-17
Now a man came up to Jesus and asked, “Teacher, what good thing must I do to get eternal life?” “Why do you ask me about what is good?” Jesus replied. “There is only One who is good. If you want to enter life, obey the commandments.”
NIV1984 1 John 2:3-6
We know that we have come to know him if we obey his commands. The man who says, “I know him,” but does not do what he commands is a liar, and the truth is not in him. But if anyone obeys his word, God’s love is truly made complete in him. This is how we know we are in him:
Whoever claims to live in him MUST WALK AS JESUS DID.
NIV1984 2 John 1:5-11
And now, dear lady, I am not writing you a new command but one we have had from the beginning. I ask that we love one another.
And this is love: that we walk in obedience to his commands. As you have heard from the beginning, his command is that you walk in love. Many deceivers, who do not acknowledge Jesus Christ as coming in the flesh, have gone out into the world. Any such person is the deceiver and the antichrist. Watch out that you do not lose what you have worked for, but that you may be rewarded fully.
Anyone who runs ahead and does not continue in the teaching of Christ does not have God; whoever continues in the teaching has both the Father and the Son. If anyone comes to you and does not bring this teaching, do not take him into your house or welcome him. Anyone who welcomes him shares in his wicked work.
NIV1984 John 14:21-24
Whoever has my commands and obeys them, he is the one who loves me. He who loves me will be loved by my Father, and I too will love him and show myself to him.” Then Judas (not Judas Iscariot) said, “But, Lord, why do you intend to show yourself to us and not to the world?” Jesus replied, “If anyone loves me, he will obey my teaching. My Father will love him, and we will come to him and make our home with him. He who does not love me will not obey my teaching. These words you hear are not my own; they belong to the Father who sent me.
And when you SOW to please the Spirit and reap eternal life, do you just claim salvation and do no WORKS?
NIV1984 John 4:34-38
“My food,” said Jesus, “is to do the will of him who sent me and to finish his work. Do you not say, ‘Four months more and then the harvest’? I tell you, open your eyes and look at the fields! They are ripe for harvest. Even now the reaper draws his wages, even now he harvests the crop for eternal life, so that the sower and the reaper may be glad together. Thus the saying ‘One sows and another reaps’ is true. I sent you to reap what you have not worked for. Others have done the hard work, and you have reaped the benefits of their labor.”
NIV1984 Galatians 6:7-10
Do not be deceived: God cannot be mocked. A man reaps what he sows. The one who sows to please his sinful nature, from that nature will reap destruction; the one who sows to please the Spirit, from the Spirit will reap eternal life. Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up. Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers.
NIV1984 Matthew 3:10
The ax is already at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire.
" No deceiver would truly teach OBEDIENCE TO GOD and no true Christian would teach DISOBEDIENCE TO GOD."
