Marriage is very difficult for many today, many are enduring their marriage only very few are enjoying their Marriage. Though many people are quick to blame in laws, jobs, spouses etc for the state of their Marriage. The truth is many makes very terrible mistakes that hurts their Marriage greatly. Here I will expose seven of these mistakes.
1) RUNNING MARRIAGE WITHOUT GOD
 Except the Lord build the house, they labour in vain that build it: except the Lord keep the city, the watchman waketh but in vain.
 It is vain for you to rise up early, to sit up late, to eat the bread of sorrows: for so he giveth his beloved sleep.
2) ENTERING MARRIAGE THROUGH NEGATIVE DOORS
Psalm 11:1-3 KJV
 In the Lord put I my trust: how say ye to my soul, Flee as a bird to your mountain?
 For, lo, the wicked bend their bow, they make ready their arrow upon the string, that they may privily shoot at the upright in heart.
 If the foundations be destroyed, what can the righteous do?
EXAMPLES OF NEGATIVE DOORS
Sinful Wedding Door
3) GOING INTO MARRIAGE CLUELESS
 The Lord by wisdom hath founded the earth; by understanding hath he established the heavens.
 By his knowledge the depths are broken up, and the clouds drop down the dew.
— lack of wisdom is the greatest singular killer of marriage
— If you are not well equipped to build a marriage, you will end up wrecking a home
4) ALLOWING THIRD PARTIES TO RULE IN THEIR MARRIAGES WHO ARE THIRD PARTIES?

Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.

 But whoso committeth adultery with a woman lacketh understanding: he that doeth it destroyeth his own soul.
 A wound and dishonour shall he get; and his reproach shall not be wiped away.
7) NOT GIVING ROOM FOR COUPLE’S TIME
Song of Songs 7:11 KJV
Come, my beloved, let us go forth into the field; let us lodge in the villages.
~ The more time you spend with each other, the better both of you will understand each other.

someone else’s arms
