A short but precise instruction from the word of God to His children is to “rejoice always” 1 Thessalonians 5:17. This implies that no situation whatsoever should stop a child of God from rejoicing.
A child of God must choose to rejoice in every situation.
Hab.3:17-19 asv. tells us of the decision of prophet Habakkuk to rejoice no matter what the situation is.
Rejoicing always is a decision we must make as children of God as a directive from on High, this is majorly because strength from God comes through joy Nehemiah 8:10 asv.
God’s presence is full of joy Psalm 16:11 asv and we must choose to reside there always, enter into the presence of God through prayer, through the Word or through praise when your joy seems to be diminishing.
A christian must protect and preserve his or her joy and let it not be stolen by the evil one, it must be guarded jealously. For when you are joyous then you are strong.
Finally be strong in the Lord and in the power of His might Ephesians 6:10 asv.
It is the will of God that we should be filled with joy at all times.
