Not all desires are of God, so not all desires are to be followed up on. The dictionary defines lust as longing desire; eagerness to possess or enjoy; having an eager, passionate, and especially an inordinate or sinful desire.
Godliness must be at the centre of all your desires in life. This would create in your life a boundary of what you can have and how best to obtain it, so that at the end of everything you will be enjoying the blessings of the Lord which comes with no sorrow.
Sometimes those desires might not be wrong but when you are willing to do anything including walking in direct disobedience to the Word of God then there is a problem. Don’t do it.
Contentment on the other hand is the state of being satisfied, the ability to have gratification, pleasure and satisfaction. It is rest or quietness of the mind in one’s present condition; freedom from discontent. Paul said in Philippians 4:11 “… for I have learned how to be content (satisfied to the point where I am not disturbed or disquieted) in whatever state”.
A content person is one who trusts God and rather than moaning and grumbling for what they do not have in their relationship, they choose to take great pleasure in enjoying all that is available and then trusting completely in God for help; and are confident that God will not disappoint.
Ask God to bless you with a contented heart, such that you can enjoy everything God has made available to you in your spouse.
