The power of praise is one that cannot be overemphasized, praise is an important weapon to bring God into our situations and battle.
ACT 16:25
25 But about midnight when Paul and Silas were praying and singing hymns of praise to God, and the prisoners were listening to them;
From the above scripture, we can say that praise is a spiritual weapon that releases us from any form of prison or bondage. If we praise God we must do so in faith, because anything out of faith is sin, thus until we praise God in faith, it will not bring about our desired turnaround.
Praise must be done from the heart and also must be done expectantly. Thinking too much about the challenges of life and comparison are the major factors that causes hindrance to the blessing of praise, and the only way to access the blessing of praise is through obedience - Deuteronomy 28:1 (Now it shall be, if you diligently listen to and obey the voice of the Lord your God, being careful to do all of His commandments which I am commanding you today, the Lord your God will set you high above all the nations of the earth)
In conclusion, we must be willing to praise God in both good and bad times, for he is the God that maketh all things work together for our Good.
