There is a difference in knowing God today and knowing about God. Most people know about God from things they have observed or heard. Your parents may have talked to you about God. You may attend church to hear sermons about God. However, knowing about God is not knowing God today.
The only way you can know God today is by faith. He who comes to God must believe (Hebrews 11:6). You cannot come to God any other way. Because God is Spirit (John 4:24) you cannot see Him. Only faith can usher you into the presence of God.
The only way to know God is when He reveals Himself to your heart. When we say heart, we mean your mind, will, and emotions. God touches your heart through the gospel of Jesus Christ, that you can find faith to trust Him. Those who know God today are looking unto Jesus, the author and finisher of our faith (Hebrews 12:2).
Those who know God today, walk with Him. He becomes your daily companion. You can only walk with God by faith. For we walk by faith, not by sight (2 Corinthians 5:7). Faith assures you that God is with you today, and everyday. Faith is the assurance that God hears your prayers. Yes, faith is the evidence. For those who know God today, faith is the evidence of things not seen (Hebrews 11:1).
