"If I regard iniquity in my heart, The Lord will not hear." - Psalm 66:18 NKJV
What an interesting passage. 'Regard' is the Hebrew word ra'ah (Strong's H7200). It means to perceive or observe. 'Iniquity' is aven (H205) and it means trouble, vanity or idolatry.
The picture is one of a person who sees something out of place but just leaves it there even though they have the power to remove it. In this case it's not dirty dishes in a sink. The place is the heart which is the center of a person's being.
Here is the verse in context.
"Come and hear, all you who fear God, And I will declare what He has done for my soul. I cried to Him with my mouth, And He was extolled with my tongue. If I regard iniquity in my heart, The Lord will not hear. But certainly God has heard me; He has attended to the voice of my prayer. Blessed be God, Who has not turned away my prayer, Nor His mercy from me!" - Psalm 66:16-20 NKJV
This is a person who is aware that God has already done something great for them and lives with thanksgiving in the center of their being. They weed their garden and iniquity is removed as soon as it is seen.
"If any of you lacks wisdom, let him ask God, who gives generously to all without reproach, and it will be given him. But let him ask in faith, with no doubting, for the one who doubts is like a wave of the sea that is driven and tossed by the wind. For that person must not suppose that he will receive anything from the Lord; he is a double-minded man, unstable in all his ways." - James 1:5-8 ESV
Do doubts arise? Of course they do. But the person who weeds them out and dwells on the finished work of Christ is asking and receiving. They see their heart as a stewardship.
"Rejoice in the Lord always; again I will say, rejoice." - Philippians 4:4 ESV
This person commands their soul like a gardener commands a garden and has power because God's mercy is a good water source.
"In that day, "A pleasant vineyard, sing of it! I, the LORD, am its keeper; every moment I water it. Lest anyone punish it, I keep it night and day;" - Isaiah 27:2-3 ESV
"A garden enclosed Is my sister, my spouse, A spring shut up, A fountain sealed." - Song of Songs 4:12 NKJV
God help us. Help us to quickly weed blame out of our life and live a life of thanksgiving for what you have done. We all deserve Hell but You have given us grace. Make us quick to pull weeds as we see them so they do not multiply.
Thank You God. You answer prayer. We live now in what You have done and we know that your mercy is turned toward us and not away from us. Thank You God.
