How does one pray? With your whole soul and heart. Prayer is simply a conversation with God. After all to be friends with God, one must spend time with Him :). Just like you do with your friends here on earth. It can be about your good days or your bad. It can be a Thank You or about your own concerns and worries. God loves you. When in doubt, simply ask Him to send the Holy Spirit to pray with you, or for you 🙂
And God will, because He loves you.
And always pray in Jesus’ name. It truly makes a very real difference 🙂
