Man has power or exousia (the royal right) over his own will.
1 Corinthians 7:37 Nevertheless he that standeth stedfast in his heart, having no necessity, but hath power over his own will, and hath so decreed in his heart that he will keep his virgin, doeth well.
1 Cor 7 says:
7 Only let each person lead the life that the Lord has assigned to him, and to which God has called him. This is my rule in all the churches. 18 Was anyone at the time of his call already circumcised? Let him not seek to remove the marks of circumcision. Was anyone at the time of his call uncircumcised? Let him not seek circumcision. 19 For neither circumcision counts for anything nor uncircumcision, but keeping the commandments of God. 20 Each one should remain in the condition in which he was called. 21 Were you a slave when called? Do not be concerned about it. (But if you can gain your freedom, avail yourself of the opportunity.) 22 For he who was called in the Lord as a slave is a freedman of the Lord. Likewise he who was free when called is a slave of Christ. 23 You were bought with a price; do not become slaves of men. 24 So, brothers, in whatever condition each was called, there let him remain with God.

36 If anyone thinks that he is not behaving properly towards his betrothed,
if his[j] passions are strong, and it has to be, let him do as he wishes: let them marry—it is no sin. 37 But whoever is firmly established in his heart, being under no necessity but having his desire under control, and has determined this in his heart, to keep her as his betrothed, he will do well. 38 So then he who marries his betrothed does well, and he who refrains from marriage will do even better.
