It seems to me there are at least three ways that God communicates to us today:
1. Through His Word – the Holy Bible.
2. Through nature.
“The heavens declare the glory of God;
the skies proclaim the work of his hands.”
~ Psalm 19:1
3. Through providential actions – for example if you are praying for healing, and according to the doctors, the odds that you will get healed are nil, and yet still you get healed… that was God.
Two things to note:
Note 1: This last one – providential happenings – is one that we have to be very careful about since we can be way off in our assessment as of what is from God and what is not.
Note 2: God is constantly communicating to us.
All that said … It seems to me that there are two ways that we communicate to God today:
1. Through our words – that is, through prayer.
2. Through our actions.
~ So for example, if we are going on a journey, and prior to starting up our car, we pray for travel mercies, then we communicate one thing to God. However if while on the journey we speed and drive rambunctiously, we communicate another thing.
What is it that we communicate? We communicate that we really do not want His travel mercies.
One thing to note:
Note 1: We too are also constantly communicating with God, whether we realize it or not, whether its deliberate or not. Our actions are constantly sending a message to God.
