Ecclesiastes 8:1, NCV “No one is like the wise person who can understand what things mean.”
#1 – Ask God for it. God and His Word are the cleaning agents. A clean heart has to be created and maintained for the rest of your life.
#2 – The key is learning to stay close to God’s presence. To have joy restored, you have to have had it. Once you have it, you will want it again. God not only wants joy restored, but He will also restore it. Where sin abounds, grace abounds much more; confess, accept God’s forgiveness, get your priorities right where God can restore your joy.
Psalm 51:12, NKJV “Restore to me the joy of your salvation, And uphold me by Your generous Spirit.”
