But as for you, continue in what you have learned and have firmly believed, knowing from whom you learned it and how from childhood you have been acquainted with the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be competent, equipped for every good work. (2 Timothy 3:14-17)
My son, if you receive my words and treasure up my commandments with you, making your ear attentive to wisdom and inclining your heart to understanding; yes, if you call out for insight and raise your voice for understanding, if you seek it like silver and search for it as for hidden treasures, then you will understand the fear of the Lord and find the knowledge of God. For the Lord gives wisdom; from his mouth come knowledge and understanding... (Proverbs 2:1-6)
On several separate occasions, Jesus told the disciples to be careful and not worship like the hypocrites do, who wanted to be seen worshiping God in order to gain favor among men. In other words, God takes note of things done in private. Christ even makes it clear that several things should be done in private: charitable giving, individual prayer, and private fasting. Here at The Church at Chantilly, we encourage all believers to engage in private (individual) worship.
For those that don't yet have an active private life that includes private worship, we encourage you to read our page regarding family worship. The activities included in family worship are also those included in private worship. The difference is that the focus for private worship is for the individual to have private time alone with God: praising him, sharing your heart with him, loving him, and learning from him.
If you have trouble getting started, begin by finding a quiet place where you are not likely to be disturbed. There are a number of devotionals available for download that are useful to guide you as you spend some time reading your Bible. Pray whatever is on your heart and learn to speak to God as though he was a special friend, a loving father, a close companion. Thank him for the things you are most thankful for. Ask for his help with whatever issues you are struggling with. The important part is just that you communicate. Learn to listen to His Spirit within your heart as you pray.
