However, it is wise for couples to continue to guard their hearts. When couples find their only emotional support in one another, they set themselves up for heartbreak.There should be private portions of a heart that a person shares only with his or her spouse.In essence, Paul is saying that we need to learn to control ourselves.We are not to take advantage of others – whether it's taking physical liberties or pressing for another type of intimacy.Our relationship with God is perhaps the most intimate thing we have.When we invite others into this, we are inviting them into intimacy. First Thessalonians 4:3-7 says, "For this is the will of God, your sanctification: that you abstain from sexual immorality; that each one of you know how to control his own body in holiness and honor, not in the passion of lust like the Gentiles who do not know God; that no one transgress and wrong his brother in this matter, because the Lord is an avenger in all these things, as we told you beforehand and solemnly warned you.There is a difference between a hug of greeting and a long embrace.Each person should be aware of the meaning he or she attaches to certain gestures when considering appropriate boundaries.
It is inappropriate to have sex, in any form, prior to marriage.
Emotional intimacy occurs when couples share their inner thoughts with one another and rely on one another for emotional support.
To an extent, dating couples will become increasingly emotionally intimate. As people begin to know and trust one another, they become more deeply emotionally linked.
One way married couples strengthen their relationship is by praying together. But the manner in which they pray should preserve their personal boundaries. For God has not called us for impurity, but in holiness." (See also Colossians 3:5 and Galatians -24).
While this passage primarily applies to physical boundaries, it can also cover other areas of intimacy.
