Yesterday I gave you four steps to take to become a Christain. It involves accepting that you are a sinner, believe that Jesus Christ died for all your sins and confessing your sins and we see that Jesus Christ will cleanse you and you will be a part ofthe Kingdom of God. 
These verses aim to let us know that Jesus Christ will never leave us alone. As a new child of God, you must do these things. Read God's word, the Bible daily. This book is God's love letter to us.
Next, talk to Him daily. Get to know your heavenly Father through prayer.
Another aspect of growth is having fellowship with the saints. Here you will grow, learn and share with each other.
