seeking to increase faith is a sign of low faith.  You don’t “get” a pure heart you already have it.  You have to keep it that way.  

Nobody is doubting that, everyone agrees that people should get married early. However, many people are not able to get married soon and have to wait for a decade or even more after puberty. This is for reasons beyond their control and they have no choice in this.  There are also some scenarios where people really cannot get married for extended periods, for example people who are prisoners. 

I commend you for providing me with such a vivid explanation, however if an individual denounces their belief in Islam, Allah, and the Prophet then that person has made it evident to the people that his “Aqeeda” differs from theirs. unlike a hypocrite who is like a disease spreading falsehood, corruption, and indemnity. Therefore how can an individual who has made it apparent to the people his dismay from the religion of Islam be one who might poison it within, other then of course spreading their own deviated beliefs and misconceptions which can be adequately reprimanded through a concise and logical rebuttal which would serve in perhaps aiding the conviction of the Muslim community as they see that attacks from exterior or opposing parties can be negated through rationale. Other then just silencing their breathes.

Salam,  Islam discourages being unmarried (or delay it) when we are able to get married, let alone for long periods.  Being unmarried for long periods is not from the teaching of Islam. "Marry the single people from among you and the righteous slaves and slave-girls. If you are poor, Allah (سُبْحَانَهُ وَ تَعَالَى) will make you rich through His favour; and Allah (سُبْحَانَهُ وَ تَعَالَى) is Bountiful, All-Knowing." (Surah 24, Verse 32) In this verse, Allah (سُبْحَانَهُ وَ تَعَالَى) commands us (by Him using the imperative form of the verb) to marry the single, righteous man/woman from among us. Allah (سُبْحَانَهُ وَ تَعَالَى) even gives us a guarantee that if we are poor or lack the proper funds, still we should not delay the marriage as Allah will take care of the couple and grant them bounties from His Grace and Mercy. "And let those who cannot find someone to marry maintain chastity until Allah (سُبْحَانَهُ وَ تَعَالَى) makes them rich through His favours ..."(Surah 24, Verse 33) In the continuation of Surah 24, in the above quoted verse, Allah (سُبْحَانَهُ وَ تَعَالَى) commands the believers to remain chaste and faithful if they cannot find a suitable spouse to marry until Allah (سُبْحَانَهُ وَ تَعَالَى) grants them bounties out of His favors. Thus, one must not resort to evil, sin or illicit sexual relationships because they cannot find a permanent spouse. The Messenger of Allah (S) has said, "Of my tradition is to marry. So then whoever turns away from my tradition (Sunnah) is not from me (my nation)."   It has been narrated from Abi Abdillah that, "A man once came to my father. My father asked him, "Are you married?" The man replied, 'No.' My father (عليه السلام) replied, 'I would not love to have the world and all that is contained within it if it meant I had to spend one night without a woman (beside me).'" Humans make too many excuses to delay in marriage.
