Regular times of prayer are good, needless to say, whether individual or corporate, but I am learning why the Apostle Paul wrote in Thessalonians ( 1 Thessalonians 5 v17) to pray without ceasing, because the needs are so deep, and many and varied that they cannot be contained in one daily session. The Holy Spirit might bring to mind any particular need at any particular moment, and we need to learn to be ready and responsive as we live in expectation of such promptings. To pray without ceasing does not mean to pray non-stop which isn't humanly possible, but rather it means to be in an attitude of "constantly recurring " ejaculatory prayer.
So also with praise, song services and praise sessions are wonderful to say the least, but, additionally, David the sweet psalmist of Israel said that God's praise would continually be in his mouth (Psalm 34 v1) and that his tongue would talk of God's praise all the day. (Psalm 35 v28) Let us learn to offer up praises spontaneously throughout our days, spread over the course of the day, for it is a blessing to God. He uses it also to change the atmosphere around us. David said he would praise God seven times a day, (Psalm 119 v164) and that is a lot more do-able than we may realize!
