Not everyone struggling to exercise self-control in this area will necessarily be able to find someone appropriate to marry. The presence of significant sexual desires does not justify disobeying other biblical commands about, say, not marrying someone of the same sex or someone who does not share our faith in Christ. We can’t just take 1 Corinthians 7:9 on its own and deduce from it that God now somehow owes us some form of sexual intimacy.
