If you believe in the one, true, living God (Eph. 4:6; 1 Thess. 1:9), you can be tremendously blessed! If you believe in the deity, death and resurrection of Jesus Christ (Rom. 10:9; 1 Thess. 4:14), you can be tremendously blessed! If you believe in the inspiration, inerrancy and infallibility of the Bible (2 Tim. 3:16-17; Jas. 
1:25; 1 Cor. 2:9-13), you can be tremendously blessed! If you believe in the divine, unique, singular nature of the kingdom/ church of Christ (Matt. 16:18; Eph. 4:4; 1 Cor. 15:24), you can be tremendously blessed! If you believe in the narrow, difficult and restricted path to heaven (Matt. 7:13-14, 21-23; Eph. 4:5; John 14:6), you can be tremendously blessed! If you believe in the defined, conditional and unalterable plan of salvation (Mark 16:15-16; Acts 2:38; Rom. 10:9-10; Gal. 3:26-27), you can be tremendously blessed! If you believe in the joy, satisfaction and peace that can come only from serving God (Gal. 5:19-21; Phil. 4:4-7; 1 Cor. 15:58), you can be tremendously blessed!
Those in Christ are blessed immeasurably more than we can even imagine (cf. Eph. 1:3)!
