There's a Gospel Song (Which I think has become a Hymn, but I'm not sure) by Bill and Gloria Gaither called "Because He Lives" (You couldn't tell from the title that's where I was going, could you?). The Chorus is catchy, but also so amazing that I don't mind getting it stuck in your head (since it's stuck in mine right now anyway):
Because He lives, I can face tomorrow,
Because He lives, all fear is gone;
Because I know He holds the future,
And life is worth the living,
Just because He lives!
What I love most about this song is that it is a great reminder that this world is not our home, our goals are not here, and it is by Christ, and in Him alone, that we can face the new day. Yet I want to encourage you, just don't sing it. In fact, when you sing songs or hymns, or repeat verses to yourself, don't merely let them be words escaping your lips, but seek to make promises to God through those words. Stand upon them! Seek Jesus out in everything you do so that, because He lives, you can have life in Him. Romans 8:1-11 There is therefore now no condemnation for those who are in Christ Jesus. For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death. For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh, in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit. For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit. For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace. For the mind that is set on the flesh is hostile to God, for it does not submit to God's law; indeed, it cannot. Those who are in the flesh cannot please God.
You, however, are not in the flesh but in the Spirit, if in fact the Spirit of God dwells in you. Anyone who does not have the Spirit of Christ does not belong to him. But if Christ is in you, although the body is dead because of sin, the Spirit is life because of righteousness. If the Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you.
