I believe sometimes it is a very good idea to write down some of your prayers in a journal. It helps me when I am having trouble articulating my needs before Him. Over a period of time you have a record of how you are growing in faith. What I am finding too, after a period of time saying the same prayer over and over again like we do with the Hail Marys in the rosary, God will often rearrange your prayers here and there, by giving you the perfect word with deeper meaning than the one you chose for yourself. I believe writing things down opens you up for deeper communications of The Holy Spirit. In time you will notice God is speaking to you. Once this becomes natural to you then you seem to notice Him giving you words of knowledge while you are doing your day to day activities in the world. It seems writing my thoughts down is one of the quickest ways for me to hear His voice. I suppose for some people it could happen when they are painting and maybe for somebody else it be gardening. There is no harm in trying different ways to open yourself up to God.
I have been writing down different declarations and finding a great deal of joy using different scriptures and personalising them and then sometimes putting a few verses together. To strengthen my faith. For example if I want to pray for courage I will use verses from scripture on that subject, if it is healing I use verses from scripture on healing. Below is an example of what I mean. I wanted to pray that God’s children will grow in knowledge of Gods truth and receive His divine help. So I used Psalm 25:5 and Isaiah 45:2 and put both together in one prayer.
I Declare before Your Divine Mercy in union with all the inhabitants of Heaven in Y’shua (Jesus) Name that I and all Your beloved children be led by Your truth and teach us, for You are the God who saves us. All day long may we put our hope in You. As You have said ‘I will go before you and make the crooked places straight, I will break in pieces the gates of bronze and cut the bars of iron.’ And You have also said that Your words does not come back void. So may it be as You have promised.
Try it for yourself. It is a great deal of fun and it is a powerful way to pray.
