Priority Position

Jesus demands Himself as priority in the lives of those who deem themselves His disciples. Grant you, the Holy Sprit instructs through Paul to take care of blood family and your spiritual family, but not at the expense of Christ being everything in your life, especially first in everything. 

Paul says in Galatians 6:10 about our fellow brothers and sisters in Christ - "Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers."

Then again, in his first letter to his protege - Timothy - Paul also stresses the importance of taking care of blood family -

"Anyone who does not provide for their relatives, and especially for their own household, has denied the faith and is worse than an unbeliever." (1 Timothy 5:8)

The words of Jesus, recorded in Luke 14:26 use a strong word to convey priority or loving less than Himself - the word "hate".

"'If anyone comes to me and does not hate father and mother, wife and children, brothers and sisters—yes, even their own life—such a person cannot be my disciple.'"

"The word hate in Luke 14:26 deserves a closer look. In the Hebrew Scriptures, the contrast between “love” and “hatred” is sometimes used to communicate preference. For example, in dealing with inheritances in polygamous marriages, the Mosaic Law referred to “two wives, one beloved, and another hated” (Deuteronomy 21:15, KJV). This is a good, literal translation. There was a “loved” wife and a “hated” wife. Other translations usually soften the “hated” wife to be “unloved” (CSB) or “less loved” (NET). The law was not indicating emotional hatred on the part of the husband, only preference. One wife was preferred over the other. We have a similar use of the love/hate idiom in Malachi 1:2–3 (cf. Romans 9:13).

Some other translations make Jesus’ meaning a little clearer: “If you want to be my disciple, you must hate everyone else by comparison” (Luke 14:26, NLT, emphasis added), and the Amplified Bible says that a follower of Christ must “hate” his family members “in the sense of indifference to or relative disregard for them in comparison with his attitude toward God.” It is a “hatred” by comparison, not an absolute hatred.

We must not forget that included in Jesus’ condition that a follower must “hate” his father and mother is the condition that he likewise hate “even his own life” (Luke 14:26, NAS). Jesus is not teaching an emotional hatred of one’s parents any more than He is teaching self-hatred. The emphasis is on self-denial and absolute surrender. Immediately following is Jesus’ instruction to “carry your own cross” (verse 27, NLT)."

The context of this verse is the cost a potential believer in Christ will pay for placing their trust and belief in Jesus as their personal Lord, Savior and King. The imagery used is that of a builder sitting down and counting the cost before starting construction. 

Likewise, as Christians begin to build a life through marriage, they should be mature enough in their faith to recognize they, like Paul, don't need the other in life, but God has blessed each of you with the other to enhance life (1 Corinthians 7). The Christian life should always, single or married, reflect the awesome priority of Christ in and over our lives.

Said another way, Jesus says to us in this Luke passage, nobody else in our lives should receive any projected everything of God. Our mothers should not be first and ultimate comforter in the home. Our fathers should not be first and supreme provider of the home. Our brothers and sisters should not be first and the greatest source of support. Our wives should not be first and not encompass our idea of all God's blessings. Even we should not be first. Believers should deny themselves and place others before ourselves, but even before others God should always take the Priority Position.
