Yes, there certainly is a way back to God -- and the reason is because God wants you back! He doesn't want you to drift through life apart from Him; He loves you and wants you to be close to Him every day.
Have you asked yourself what might have caused you to drift away from God? (Remember: He hasn't moved away from you; instead, you have moved away from Him.) Is it because of a particular sin in your life -- something you know is wrong, but you've still tolerated it and allowed it to come between you and God? It may not be anything obvious to others; it may instead be hidden, or something you aren't even aware of, such as pride, jealousy, greed or laziness.
Or is it perhaps because you never did anything to strengthen your faith -- not reading the Bible, seldom praying, ignoring fellowship with other believers? I'm thankful you once felt you loved God, but our emotions can fade over time. Our faith needs to be grounded instead in the truths of God's Word, and in our daily walk with Christ.
Whatever the problem, confess it to God and ask Him to forgive you. Then recommit your life to Jesus Christ and learn to walk with Him every day. The Bible says, "If we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin" (1 John 1:7).
