God doesn't say all your friends have to be on the same spiritual level as you. Look at Jesus, He socialized with sinners and tax collectors[Luke 5:29-32]! However, if you're planning on becoming really intimate with someone, the Bible DOES say not to be unequally yoked [2 Corinthians 6:14]. Being married (for example) to someone who doesn't share your desire for God and/or is not up to being a spiritual leader in your family will bring you much sorrow and discouragement over the years. They may eventually turn to God [1 Peter 3:1], but you can't count on that, and I think you'd be better off waiting for God to work in their life BEFORE you commit yourself to them. If you're considering dating or marrying this friend and you believe this is the person God has chosen for you, then you can trust God to bring it about His Way and in His time. I can tell you from experience that waiting on the Lord is the better way, and Jesus never fails in His love for us. Don't rush ahead of God. You can have a positive impact on your friend's life and God can use you to minister to him. Just be sure that's what God wants you to do, because your friend can also have an influence on you. Give it a lot of prayer, seek more godly counsel, and spend time in God's Word. Ask God to make His answer clear to you. Your friend is not going to hinder your blessings or God hearing your prayers, it's your own obedience or disobedience that affects your relationship with the Father...and even then, nothing can separate you from His love [Romans 8:38-39]. God Bless!
