writing prayer

00When writing prayer, are these tenses correct?02br

00Thank you, God. You made me/him grow in Your Spirit so that I/he would eventually understand and be able to bring healing to the lame. 02br

00The use of 'would understand' seems tio be fine, but I am not too sure of 'would be able to' to fit into the past time frame of the overall sentence.02br

00Also, do you feel the use of a comma before 'so' is necessary. A lot of explanations seem to be here in this forum but to say that the placement of a comma in situations like hinges upon the fact that whether or not it can be replaced with 'because' to show a direct cause and result is sometimes not so effective, as it seems to me.0-
