As Christians, we should not serve God only because we want to go to Heaven.
We should serve God out of the pure love that we have for Him as our creator. And for the desire that we have to spend all eternity with Him.
Heaven is not the reason why we turn to God. Heaven is just an eternal gift we get as children of God and not the ultimate reason why we repent.
Matthew 6:33 says ''seek first the kingdom of God and all His righteousness and all these things shall be added unto you''
In this scripture God tells us to not only seek His kingdom (winning souls) but also His righteousness
And only then shall all these things be added unto us ( heaven for instance)
IN ALL YOUR SEEKING, SEEK GOD
I hope it makes some sense. Be blessed family!!!
