Talking to yourself, is it normal? It's safe to assume you've talked to yourself at least once today, and if we're being honest we probably do it more than we'd like to admit. But is it normal? To find the truth, we have to start with the bible, what does God's word teach us about talking to yourself?
Several places in scripture we read how king David talked to himself:
Psalm 103:1-2 "Bless the Lord, O my soul: and all that is within me, bless his holy name. Bless the Lord, O my soul, and forget not all his benefits:"
Psalm 104:1 "Bless the Lord, O my soul. O Lord my God, thou art very great; thou art clothed with honour and majesty."
Psalm 104:35 "Let the sinners be consumed out of the earth, and let the wicked be no more. Bless thou the Lord, O my soul. Praise ye the Lord."
Psalm 146:1 "Praise ye the Lord. Praise the Lord, O my soul."
Psalm 103: 22 "Bless the LORD, all his works in all places of his dominion: bless the LORD, O my soul."
Psalm 77:6 "I call to remembrance my song in the night: I commune with mine own heart: and my spirit made diligent search."
Most notebly, Psalm 77:6. David suffered a lot of turmoil in his life, from being innocently persecuted by king Saul, who tried to kill him every chance he got, to losing a new born baby, to losing his best friend Jonathan by the hand of the Philistines, David went through a lot. It's evident David's life was a shadow of the coming Christ, and a shadow of the complete rejection Jesus Christ faced from all mankind as he was crucified on the cross for all our sin. But Psalm 77, like many of the psalms, is a glimpse into David's prayer life and gives us insight into how he dealt with turmoil.
In this chapter, David is crying out to God and is overwhelmed with turmoil. In the first few verses David describes his grief, 2-4 "...my soul refused to be comforted. I remembered God, and was troubled: I complained, and my spirit was overwhelmed. Selah. Thou holdest mine eyes waking: I am so troubled that I cannot speak."
With trouble overwhelming him, David begins to speak to his heart, "I call to remembrance my song in the night: I commune with mine own heart: and my spirit made diligent search." David asks his heart 6 rhetorical questions; "7 Will the Lord cast off for ever? and will he be favourable no more? 8 Is his mercy clean gone for ever? doth his promise fail for evermore? 9 Hath God forgotten to be gracious? hath he in anger shut up his tender mercies? Selah." The answer to all these questions is no, but that's the point! With no one there to encourage him, he did it himself!
Sometimes, when we are in a spiritual valley, we need to remind ourselves who we serve. We need to speak to our hearts and tell our hearts not to worry, but instead to trust in Jesus Christ. We need to remind our hearts of how big God is, how magnificent His works were against Egypt, how Christ walked on water, how He rose from the third day and set us free! Give it a try, tell your heart not to worry, tell your soul to bless the Lord (Psalm 103:1)!
So yes, according to the Word of God it is normal to speak to yourself. But each time the purpose is to encourage the person to serve the Lord and bless His mighty name. And if it's not for Christ, or to bless His name, why do it?
