Are you feeling distant from God?
Do you remember what it was like when you first felt God's love? Have you lost that?
Have you allowed sin to harden your heart?
Do you need to experience the joy of salvation again?
Ask God to search your heart and see if there's anything, any thoughts, beliefs, desires, emotions or things that you are doing that you need to get rid of. Pray Psalm 139:24 see if there is any offensive way in me and lead me in the way everlasting. If God reveals anything to you, repent and ask him to help you remove that from your life.
Like David, come to God in genuine repentance, asking him to create in you a clean heart and renew a steadfast spirit within you. Psalm 51:1012 I believe with all my heart that prayer will change your life. It's a prayer God answered for David and he will answer you too.
