Just pray means, just ask.
God has made many kinds of promises to encourage us to pray:
But let’s not make a legalistic condition out of what was intended to be a gracious encouragement.
If you pray according to God’s will …
If you pray in Jesus’ Name …
If you pray in faith …
If you quote God’s promises …
If you pray in the words of Scripture …
If you pray persistently …
The “ifs” are not conditions, in the sense that God is looking for a flaw in the prayer, a loophole, which will let Him ignore the prayer and not answeer it!
