Look bro where in the bible is it recorded that God called someone be alone ?? Edify me ..
Okay here is 3 scriptures which the Lord taught to His disciples:
Mat 19:10 His disciples say unto him, If the case of the man be so with his wife, it is not good to marry.
Mat 19:11 But he said unto them, All men cannot receive this saying, save they to whom it is given.
Mat 19:12 For there are some eunuchs, which were so born from their mother's womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it.
Then Paul wrote this about men or women to be single:
1Co 7:6 But I speak this by permission, and not of commandment.
1Co 7:7 For I would that all men were even as I myself. But every man hath his proper gift of God, one after this manner, and another after that.
1Co 7:8 I say therefore to the unmarried and widows, It is good for them if they abide even as I.
1Co 7:9 But if they cannot contain, let them marry: for it is better to marry than to burn.
1Co 7:28 But and if thou marry, thou hast not sinned; and if a virgin marry, she hath not sinned. Nevertheless such shall have trouble in the flesh: but I spare you.
1Co 7:32 But I would have you without carefulness. He that is unmarried careth for the things that belong to the Lord, how he may please the Lord:
1Co 7:33 But he that is married careth for the things that are of the world, how he may please his wife.
1Co 7:34 There is difference also between a wife and a virgin. The unmarried woman careth for the things of the Lord, that she may be holy both in body and in spirit: but she that is married careth for the things of the world, how she may please her husband.
1Co 7:35 And this I speak for your own profit; not that I may cast a snare upon you, but for that which is comely, and that ye may attend upon the Lord without distraction.
So you see it is possible for man and woman to not be married, for they are free to serve the Lord more readily than married people.
However, the Lord gives them the Grace to do so, and when they are called to do so. There were men of God in the OT also were not married, as according to the Lord's perfect will and purpose for the individual. That is why, no true believer in Christ can forbid anyone from not marrying.
Lord bless you......
