The question has to be asked, "Why has God chosen us?"
“If you love Me, keep My commandments. And I will pray the Father, and He will give you another Helper, that He may abide with you forever...Judas (not Iscariot) said to Him, “Lord, how is it that You will manifest Yourself to us, and not to the world?” Jesus answered and said to him, “If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him. He who does not love Me does not keep My words; and the word which you hear is not Mine but the Father’s who sent Me. (NKJV, John 14:15-24)
There are two groups in the world:
- If anyone loves Me, he will keep My word
- He who does not love Me does not keep My words
Group 1) is given manifestation, and group 2) is denied sight.
Note that John 14, says there is an action of obedience we take before the Father's love is given. How does this work:
And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed. But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God." (NKJV, John 3:19-21)
Those who delight in evil, will not come to the light, because they enjoy their wrongdoing. Those willing to go God's way, are willing to walk out of darkness into God's light.
I am sure someone will say, that we are not saved by our works, that is true. It is not our prior good deeds of righteousness, but a heart when seeing God's grace),
... but grace and truth came through Jesus Christ (NKJV, John 1:17) even the forgiveness of our past deeds, is willing to turn to God. This involves trust in the cross to forgive our sins. But also a desire to live within God's boundaries (obedience). The one not loving God, who is ungrateful, will not come to the cross, unwilling to change their lives.
But you are not willing to come to Me that you may have life. (NKJV, John 5:40)
