Besides a relationship with God, there are 3 other relationships that are important to each and every one of us. Not everyone is in all these 3 relationships at once, but at least you are likely to be in 1 of the 3 relationships. One will not experience complete joy without getting all these relationships right as the Lord intended.
Parents and children relationship - Ephesians 6:1-4
Children, obey your parents in the Lord: for this is right. Honour thy father and mother; (which is the first commandment with promise;) That it may be well with thee, and thou mayest live long on the earth. And, ye fathers, provoke not your children to wrath: but bring them up in the nurture and admonition of the Lord.
Parents have the responsibility of bringing up the children in the nurture and admonition of the Lord and children to obey the parents in the Lord. It is important to have the parent's blessings in everything you do. In the Old Testament, the Father gives blessings to his children.
Husband and wife relationship - 1 Peter 3:1,6-7
Likewise, ye wives, be in subjection to your own husbands; that, if any obey not the word, they also may without the word be won by the conversation of the wives;
Even as Sara obeyed Abraham, calling him lord: whose daughters ye are, as long as ye do well, and are not afraid with any amazement. Likewise, ye husbands, dwell with them according to knowledge, giving honour unto the wife, as unto the weaker vessel, and as being heirs together of the grace of life; that your prayers be not hindered.
The husband has a greater responsibility as a spiritual leader. Many husbands did not undertake the role of spiritual leaders to love their wives and walk with God resulting in disharmony in many instances. Prayers are hindered because of the failure to carried out God's instructions. The wife serving the Lord must obtain full support from the husband. If the husband is not comfortable with a certain way the ministry is carried out, the wives should make adjustments immediately to ensure the husband and wife relationship is not jeopardized in any way.
Believers to believers relationship - Hebrews 13:7
Remember them which have the rule over you, who have spoken unto you the word of God: whose faith follow, considering the end of their conversation.
In the body of Christ, we have same respect for everyone. This passage is particularly focused on those who have spiritual authority in the local assembly. Who teaches and guides you in the word of God as a spiritual mentor. Remember them is to hold them in a certain respect.
My we pay closer attention to these relationships and experience a deeper journey with God through them. These are the sacred relationship bestowed from God.
