Spiritual health (or lack of it) impacts you mentally, emotionally and physically.  It impacts your attitudes and your actions.  Spiritual health impacts all your relationships and is directly related to your connection (or lack of connection) with Christ.

Jesus said: Dwell in Me, and I will dwell in you. [Live in Me, and I will live in you.] Just as no branch can bear fruit of itself without abiding in (being vitally united to) the vine, neither can you bear fruit unless you abide in Me. I am the Vine; you are the branches. Whoever lives in Me and I in him bears much (abundant) fruit. However, apart from Me [cut off from vital union with Me] you can do nothing. (John 15:4, 5 AMP)

Our vital union with Christ includes a consistent connection with Him privately and publicly.

Jesus needed private time alone with God the Father (Mark 1:35).  Our time alone with God where we connect with Him privately is made possible by Jesus through His Spirit.  His Spirit (the Holy Spirit) enables us to understand Scripture and gives us an open door to talk with God (prayer) about anything at anytime.

Ephesians 4:21-24 says: Since you have heard about Jesus and have learned the truth that comes from him, throw off your old sinful nature and your former way of life, which is corrupted by lust and deception. Instead, let the Spirit renew your thoughts and attitudes. Put on your new nature, created to be like God—truly righteous and holy.

We also connect publicly with God through the body of Jesus called the church.  That connection with the body of Christ can be in small groups of believers gathering together, or in large corporate groups where we come together for public worship and wise counsel from God’s Word.  We need the encouragement / accountability of other Christians to help us in our battle with our old sinful nature and the deception of sin.

Hebrews 10:24-25 CEV states: We should keep on encouraging each other to be thoughtful and to do helpful things. Some people have gotten out of the habit of meeting for worship, but we must not do that. We should keep on encouraging each other, especially since you know that the day of the Lord’s coming is getting closer.

If you are a follower of Christ, when you cut yourself off from the body of Christ (the church) it’s like cutting off a part of your physical body.  It limits you and your spiritual health, and limits the health & balance of the church.
