Is griping about little petty stuff like music gonna expand the Kingdom???
Music will not keep people out of the Kingdom of God, it is the cares of this world, and lust, and sin that will keep people out of the Kingdom, even disobedience to Jesus Christ.
I know there are some people on here deceiving others into such rules as don't do this and don't say that or else you will not enter heaven, these people have not known grace, or either are fallen from grace. The issue is in a man's heart because out of it flow the issues of life. Where a person's treasure is, their hearts will be there too.
Anyone who loves pleasure MORE than obeying Jesus will not enter the Kingdom of God. So if you think it is easy to enter, hear what Jesus said:
23 ¶Then said Jesus unto his disciples, Verily I say unto you, That a rich man shall hardly enter into the kingdom of heaven.
24 And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God.
25 When his disciples heard it, they were exceedingly amazed, saying, Who then can be saved?
26 But Jesus beheld them, and said unto them, With men this is impossible; but with God all things are possible.
27 ¶Then answered Peter and said unto him, Behold, we have forsaken all, and followed thee; what shall we have therefore?
28 And Jesus said unto them, Verily I say unto you, That ye which have followed me, in the regeneration when the Son of man shall sit in the throne of his glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel.
29 And every one that hath forsaken houses, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my name's sake, shall receive an hundredfold, and shall inherit everlasting life.
30 But many that are first shall be last; and the last shall be first.
Matthew 19
If you want to enter you must follow Jesus, forsaking the old. May Jesus bless you.
