Psalm 50:15 And call upon me in the day of trouble: I will deliver thee, and thou shalt glorify me.
We have such a relationship with the Lord that we may talk to Him at any time, and He listens and answers. In particular, He commands us to call upon Him in the day of trouble. He promises to answer our need and deliver us from the present trouble, whether it be health, finances, accidents, family and relationships. In some sense every day is a day of trouble.
Jesus cares, hears, answers, delivers, and He is always with us. We sense a need for Him especially in the day of trouble. Therefore, we call upon Him to meet our need, and He delivers us from the trouble. He has already delivered us from the biggest trouble of sin and death. That deliverance extends throughout our lifetime and into eternity.
When He delivers, and we are aware of it because we prayed, then we will glorify Him. As we pray without ceasing so we praise and thank Him without ceasing, for God is always good.
