People believe in the existence of God, yet they have no idea what kind of God they would accept. For me, Christ is the true God from both the subjective and objective points of view. You can believe in some god, but only the true God can reveal himself to you within your heart. Love, peace, freedom, deep joy and your own transformation are all solid signs that that you have the truth.
Another mental image came to me this morning. Living our life is like walking along a precipice. If you slip, you can fall off it and plunge toward the bottom. If you do not know Christ, you may or may not survive, depending upon your circumstances and how good a person you are. If you know and believe in Christ, you can be sure you will be safe with him no matter what happens.
