This dull flesh, in its worldly leanings, needs the Lord's constant grace. This is especially true in prayer, when we are before the throne of God. It is then that the knowledge of His holiness and majesty should light a blazing fire of passionate surrender within us and obliterate anything which is not focussed solely on our communion with Him. But, sadly this is often not the case to our great shame.
As little children, prone to wanderings and weakness, sometimes we need some help remembering Who we are talking to. Something from Desiring God:
Whatever it takes, Lord, give me...
Delight in you as the greatest treasure of my heart.
Delight in the Lord and he will give you the desires of your heart. (Psalm 37:4)
Desire to know you, be with you, and seek your kingdom above all else.
Delight in the Lord and he will give you the desires of your heart. (Psalm 37:4)
Discernment that comes from a renewed mind that I might know your will.
But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil. (Hebrews 5:14)
Desperation because when I stop feeling my need for you I tend to wander.
Discipline to plan for what I discern as your will.
Look carefully then how you walk, not as unwise but as wise, making the best use of the time, because the days are evil. (Ephesians 5:15-16)
Diligence to do your will with all my heart.
You shall love the Lord your God with all your heart and with all your soul and with all your might. (Deuteronomy 6:5)
